11Electric 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… …
12Brushless 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 …
13AC motor — An AC motor is an electric motor that is driven by an alternating current. It consists of two basic parts, an outside stationary stator having coils supplied with AC current to produce a rotating magnetic field, and an inside rotor attached to… …
14Time constant — In physics and engineering, the time constant usually denoted by the Greek letter au , (tau), characterizes the frequency response of a first order, linear time invariant (LTI) system. Examples include electrical RC circuits and RL circuits. It… …
15Induction motor — An induction motor (IM) is a type of asynchronous AC motor where power is supplied to the rotating device by means of electromagnetic induction. Other commonly used name is squirrel cage motor due to the fact that the rotor bars with short… …
16DC 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 …
17synchronous motor — Elect. a synchronous machine that acts as a motor. [1900 05] * * * ▪ mechanics alternating current electric motor designed to run at a speed that is directly proportional to the frequency of the electric power source. Typically, a… …
18Electronically commutated motor — An electronically commutated motor (ECM) is a brushless motor which relies on the external power drive to perform the commutation of stationary copper winding on the stator. This changing stator field causes the permanent magnet rotor to rotate.… …
19Stepper motor — A stepper motor (or step motor) is a brushless, synchronous electric motor that can divide a full rotation into a large number of steps. The motor s position can be controlled precisely, without any feedback mechanism (see open loop control).… …
20Brushed DC electric motor — A brushed DC motor is an internally commutated electric motor designed to be run from a direct current power source. Contents 1 Simple two pole DC motor 2 The commutating plane 2.1 Compensation for stator field distortion …
