The Owen Magnetic was a pioneering [1] American brand of hybrid electric luxury automobile manufactured between 1915 and 1922. Car models of the brand were notable for their use of an electromagnetic transmission and were early examples of an electric series hybrid drivetrain. The manufacture of the car was sponsored by R.M. Owen & Company of New York, New York. The car was built in New York City in 1915, in Cleveland, Ohio, between 1916 and 1919 and finally in Wilkes-Barre, Pennsylvania, in 1920 and 1921. [2]
The first Owen Magnetic was introduced at the 1915 New York auto show when Justus B. Entz's electric transmission was fitted to the Owen automobile: "R.M. Owen have leased the large new three story fireproof building at the corner of Fifth avenue and One Hundred and Forty-second street, New York, where they will build the new Owen Magnetic motor cars." The former Owen plant still exists and is presently a self-storage facility. [3]
Raymond M. Owen and his brother Ralph R. Owen had been working on the Entz transmission adapting it for a car since 1912. [2] Justus Entz's drive train patent was U.S. Patent 1,207,732 . [4] The Entz transmission had no physical connection between the gasoline engine and the driveshaft. Walter C. Baker, of Cleveland, Ohio, owned the patents on the Entz transmission, thus each of the 250 Owen Magnetic automobiles produced in New York was built under license. [2]
Some sources wrongly state that the Woods Dual Power car manufactured by the Woods Motor Vehicle Company in Chicago also used the Entz transmission. The Woods Dual Power had a drive-train based on Roland Fend's U.S. Patent 1,303,870 , using a clutch between the gas engine and the electric motor.[ citation needed ]
The car became as famous as the company's clientele, which included Enrico Caruso and John McCormack. Owen Magnetics were advertised as "The Car of a Thousand Speeds". In December 1915, the company was moved to Cleveland when the R. M. Owen Company joined Walter Baker (of Baker Motor Vehicle) and the Rauch and Lang company. The Baker Electric Car company would produce the car, and Rauch and Lang would build the coachwork. Because of the combined resources, the Owen Magnetic increased its range of offerings for 1916 model year adding a Holbrook bodied sports tourer for $6,000, equivalent to $161,358in 2022. Production continued through 1918, with prices ranging from $3,000 to $5,000 (equivalent to $134,465in 2022), when Baker shifted its focus to war goods manufacturing. [2]
J. L. Crown secured the rights to the Entz transmission and with Raymond Owen the company reorganized as the Owen Magnetic Motor Car Corporation based in Wilkes-Barre. [2] The newly equipped factory was situated in the old Matheson works at Forty Fort, Pennsylvania. [5] The Wilkes-Barre Times announced the resumption of production for January 1, 1920, with the aim of producing 750 cars that year. [6] [2]
J. L. Crown who now owned the Entz rights, placed an order for 500 vehicles to be sold by Le Grice Elers, Ltd of London. Crown Limited of Great Britain was formed and the cars were named Crown Magnetic. However, by August 1920, before the order could be fulfilled, Owen Magnetic was in receivership. [7] The Crown Magnetic was displayed at the London Motor Show in 1920, with about 20 imported before production ceased. [8] [9]
The Crown version of the Magnetic omitted the emergency low gear fitted on the Owen Magnetics. This turned out to be a mistake, as on a long steep hill, the force of gravity on this heavy car could defeat the transmission and could bring the car to a standstill. [9]
The car was powered by a six-cylinder engine, but power was transmitted to the wheels based upon the same electromagnetic principle that propelled the Battleship U.S.S. New Mexico.
Automobile author Henry B. Lent described the drive mechanism thus:[ citation needed ]
The drive mechanism had no direct connection between the engine and the rear wheels. Instead of a flywheel, a generator and a horseshoe shaped magnet were attached to the rear of the engine's crank shaft. On the forward end of the car's drive shaft, was an electric motor with an armature fitted into an air space inside the whirling magnet. Electric current, transmitted by the engine's generator and magnet attached to the armature of the electrical motor, providing the energy to turn the drive shaft and propel the engine's rear wheels. Speed for the car was controlled by a small lever adjacent to the steering wheel.
In electricity generation, a generator is a device that converts motion-based power or fuel-based power into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all the power for electrical grids.
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines.
The Chalmers Motor Company was an American automobile manufacturer headquartered in Detroit, Michigan. Founded in 1908 by Hugh Chalmers, the company was known for producing high-end vehicles. Chalmers automobiles gained recognition for their toughness, durability, and engineering receiving particular praise for their performance in touring events. The company reached its peak in 1911, becoming the eighth-largest auto producer in the United States. Despite initial success, the company faced challenges with increasing competition in the auto industry, and sales began to decline in the following years. In 1923, Chalmers Motor Company merged with Maxwell Motor, ultimately forming the basis for the Chrysler Corporation.
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed "rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and "regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles.
A continuously variable transmission (CVT) is an automated transmission that can change through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant angular velocity while the vehicle moves at varying speeds.
A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows. The controller adjusts the phase and amplitude of the DC current pulses to control the speed and torque of the motor. This control system is an alternative to the mechanical commutator (brushes) used in many conventional electric motors.
A drive shaft, driveshaft, driving shaft, tailshaft, propeller shaft, or Cardan shaft is a component for transmitting mechanical power and torque and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them.
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, or electric multiple unit trains.
Hybrid Synergy Drive (HSD), also known as Toyota Hybrid System II, is the brand name of Toyota Motor Corporation for the hybrid car drive train technology used in vehicles with the Toyota and Lexus marques. First introduced on the Prius, the technology is an option on several other Toyota and Lexus vehicles and has been adapted for the electric drive system of the hydrogen-powered Mirai, and for a plug-in hybrid version of the Prius. Previously, Toyota also licensed its HSD technology to Nissan for use in its Nissan Altima Hybrid. Its parts supplier Aisin Seiki Co. offers similar hybrid transmissions to other car companies.
A direct-drive mechanism is a mechanism design where the force or torque from a prime mover is transmitted directly to the effector device without involving any intermediate couplings such as a gear train or a belt.

A magneto is an electrical generator that uses permanent magnets to produce periodic pulses of alternating current. Unlike a dynamo, a magneto does not contain a commutator to produce direct current. It is categorized as a form of alternator, although it is usually considered distinct from most other alternators, which use field coils rather than permanent magnets.
Car controls are the components in automobiles and other powered road vehicles, such as trucks and buses, used for driving and parking.
