A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...
Without an incentive to purchase the electric automobiles, gas automobiles were the most viable option at the time. [5] Electric cars use batteries to store electricity which is used to power electric motors. The battery delivers the power to the motor, which is either Alternating Current (AC) or Direct Current (DC).
AC electric motors can be run in fixed-speed operation determined by the number of stator pole pairs in the motor and the frequency of the alternating current supply. AC motors can be made for "pole changing" operation, reconnecting the stator winding to vary the number of poles so that two, sometimes three, speeds are obtained.
A U.S. Department of Energy report found that, when factoring in the long-term ownership expenses, a small electric SUV costs $0.4508 per mile compared to $0.4727 per mile for a comparable gas car.
An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
The first experimental electric traction motor tramway of 1875 was rapidly developed internationally for city use. [5] [6] [7] In the 19th century traction motor passenger car companies began to compete with the dominant citywide horse-drawn railway transportation system. [8] [9] [10]
[1] [2] It offers AC-induction traction motors. [3] The company produces electric vehicle drive systems featuring high performance, high efficiency induction motors and integrated high power battery charging. [3] [4] Previously, they built an electric sports car, the tzero [2] and the eBox, [2] an electric conversion based on the Scion XB. They ...
Historically, these have used aircraft starter motors and lead-acid batteries; several books have been written to document and guide these conversions, [12] including The Complete Book of Electric Vehicles (Shacket, 1979), [13] How to Convert to an Electric Car (Lucas & Riess, 1980), [14] Convert It (Brown & Prange, 1993), [15] and Build Your ...
