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 ...
An electronic speed control (ESC) is an electronic circuit that controls and regulates the speed of an electric motor. It may also provide reversing of the motor and dynamic braking. Miniature electronic speed controls are used in electrically powered radio controlled models. Full-size electric vehicles also have systems to control the speed of ...
SAE J3068 "Electric Vehicle Power Transfer System Using a Three-Phase Capable Coupler" [1] is a North American recommended practice published and maintained by SAE International. J3068 defines electrical connectors and a control protocol for electric vehicles. It has the formal title "SAE Surface Vehicle Recommended Practice J3068".
The Three EV Motor Types. The motor types can be broken down by fundamental rotor differences that represent entirely different ways of turning the stator's RMF into actual rotary motion. These ...
SAE J1772, also known as a J plug or Type 1 connector after its international standard, IEC 62196 Type 1, is a North American standard for electrical connectors for electric vehicles maintained by SAE International under the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler".
There are different ways that a hybrid electric vehicle can combine the power from an electric motor and the internal combustion engine. The most common type is a parallel hybrid that connects the engine and the electric motor to the wheels through mechanical coupling. In this scenario, the electric motor and the engine can drive the wheels ...
The traction motor(s), reduction gear, and power electronics are combined into a single Ultium Drive unit that drives the front, rear, or both axles. Three electric motor designs, sharing a common stator, are used across all planned vehicles. [4] [5] Ultium is used by GM's BEV3 and BT1 platforms. [6]
In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...
