Fleming's left-hand rule. Fleming's left-hand rule for electric motors is one of a pair of visual mnemonics, the other being Fleming's right-hand rule for generators. [1] [2] [3] They were originated by John Ambrose Fleming, in the late 19th century, as a simple way of working out the direction of motion in an electric motor, or the direction of electric current in an electric generator.
The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
Priming effects occur when the prime influences the motor response to the target: consistent primes speed responses to the target, whereas inconsistent primes slow responses (Fig. 2). Priming effects in response times are calculated by taking the difference between response times in inconsistent and consistent trials.
Motor adaptation, a form of motor learning, is the process of acquiring and restoring locomotor patterns (e.g. leg coordination patterns) through an error-driven learning process. This type of adaptation is context-dependent and hence, is specific to the environment in which the adaptation occurred.
An example of table-turning in 19th century France. A circle of participants press their hands against a table, and the ideomotor effect causes the table to tilt in such a way as to produce a written message, in a manner similar to a ouija board. [1] Faraday's apparatus for experimental demonstration of ideomotor effect on table-turning
An electrostatic motor or capacitor motor is a type of electric motor based on the attraction and repulsion of electric charge. An alternative type of electrostatic motor is the spacecraft electrostatic ion drive thruster where forces and motion are created by electrostatically accelerating ions.
The rotating magnetic field is the key principle in the operation of induction machines.The induction motor consists of a stator and rotor.In the stator a group of fixed windings are so arranged that a two phase current, for example, produces a magnetic field which rotates at an angular velocity determined by the frequency of the alternating current.
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. [ 1 ] [ 2 ] Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation ), heat energy (e.g. geothermal ), chemical energy , electric potential and nuclear ...
