The fundamental limitation of running induction motors slowly on household (60 cycle per second, 3600 cycles per minute) AC is that the motor type you have has 4 poles if it runs 1800 RPM - so you'd need 36 poles to turn 200 RPM on 60-cycle AC.
Oct 04, 2017 · The speed torque curves for this scheme are depicted in Fig. 1.28(a). The desired modification of the torque speed curves shown in Fig. 1.28(a) is achieved by controlling the slip power converter to match the motor voltage at a given slip. The control of the converter is represented by the parameter a.
Introduction: The YE2/YE3 series (IP55) high efficiency three-phase asynchronous motor is a fully enclosed self-ventilated three-phase asynchronous motor with high energy efficiency limit. This series of motor mounting dimensions is the same as Y and Y2 series, which are the replacement products of Y and Y2 series motors.
5) 3-Phase: Generally 3-phase induction motors have a high starting torque, high power factor, high efficiency, and low current. Does not use a switch, capacitor or relay for starting. Suitable for use on larger commercial and industrial applications. 6) AC/DC (Universal or Series wound): Operates on AC (60 or 50 Hz) power. High speed. Speed
