WebMar 14, 2012 · Electric motors have the great power of being capable of converting mechanical (rotational) energy in electricity and vice versa, and with a quite high efficiency. But if you need to take the energy from a "linear" movement, like from the surface of a tire, you need a gear which takes the rotation from the movement of the tire, like a dinamo. WebAn AC motor is a motor that converts alternating current into mechanical power. The stator and the rotor are important parts of AC motors. The stator is the stationary part of the motor, and the rotor is the rotating part of the motor. The AC motor may be single-phase or three-phase. Nikola Tesla invented the first AC induction motor in 1887.

Torque and Speed

WebTo calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM. You can also calculate the slip rating by ... WebA reciprocating engine is an engine that uses one or more pistons in order to convert pressure into rotational motion. They use the reciprocating (up-and-down) motion of the pistons to translate this energy.
