Question

9. Consider the following statements for a single - phase hysteresis motor : 1. Torque is constant from standstill up to synchronous speed Ns.2. Rotor is provided with narrow slots embedded with bars.3. Torque at starting is somewhat more than that at synchronous speed Ns.4. As the name suggests, only hysteresis torque is produced from zero speed right up to Ns.5. Rotor material possesses very wide hysteresis loop.Which of tilt statements given above are correct?
