12Motor controller — A motor controller is a device or group of devices that serves to govern in some 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,… …
13Electric motor — For other kinds of motors, see motor (disambiguation). For a railroad electric engine, see electric locomotive. Various electric motors. A 9 volt PP3 transistor battery is in the center foreground for size comparison. An electric motor converts… …
14Brushless DC electric motor — A microprocessor controlled BLDC motor powering a micro remote controlled airplane. This external rotor motor weighs 5 grams, consumes approximately 11 watts (15 millihorsepower) and produces thrust of more than twice the weight of the plane …
15Direct torque control — (DTC) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three phase AC electric motors. This involves calculating an estimate of the motor s magnetic flux and torque based on the measured… …
16DC injection braking — DC injection brake module [1] DC injection braking is a method of slowing AC electric motors. A DC voltage is injected into the winding of the AC motor after the AC voltage is disconnected, providing braking force to the rotor [2] …
17Amplifier — For other uses, see Amplifier (disambiguation). Generally, an amplifier or simply amp, is a device for increasing the power of a signal. In popular use, the term usually describes an electronic amplifier, in which the input signal is usually a… …
18DC motor — A DC motor is an electric motor that runs on direct current (DC) electricity. Contents 1 Brush 2 Brushless 3 Uncommutated 4 Connection types …
19Motor-generator — Radio station motor generator set, converting from low to the high voltage power supply. This device is called an umformer in German. Dübendorf Museum of Military Aviation A motor generator (an M G set or a dynamotor for dynamo motor) is a device …
20Nanomotor — A nanomotor is a molecular device capable of converting energy into movement. It can typically generate forces on the order of piconewtons. A proposed branch of research is the integration of molecular motor proteins found in living cells into… …
