In ac which gas will be use?
Difference between induction motor and synchronous motor? i Think Synchronous motors operate at synchronous speed (RPM=120f/p) while induction motors operate at less than synchronous speed (RPM=120f/p – slip). Slip is nearly zero at zero load torque and increases as load torque increases am a right pls guide & send Other Comments
