Assertion: motor's speed | /r/HasProperty | synchronous
Facets:
Source sentences:
text: Induction motors are referred to as ‘asynchronous motors’ because they operate at a speed less than their synchronous speed.
text: The induction motor always runs at speed less than its synchronous speed.
text: The motor that converts the AC electrical power into mechanical power and is operated only at the synchronous speed is known as a synchronous motor.
text: They may also be started as induction motors using a squirrel-cage winding that shares the common rotor: once the motor reaches synchronous speed, no current is induced in the squirrel-cage winding
text: The motor then runs at synchronous speed as if the rotor were a permanent magnet.
text: For a given design, torque at synchronous speed is only relatively modest, and the motor can run at below synchronous speed.
text: Brushless DC motors are powered by a pulsed DC supply to create a rotating field and the speed is synchronous with the frequency of the rotating field.
text: As the motor approaches synchronous speed it will suddenly snap in to synchronisation.
text: As the motor approaches synchronous speed the magnetic effect of the crossbars behaving like a permanent magnet causes the motor to lock on to synchronous speed.
text: During run up it behaves as an induction motor but as it approaches synchronous speed, the reluctance torque takes over and the motor locks into synchronous speed.
text: Rest all are AC electric motors and are driven by alternating current, for, e.g., the synchronous motor, which always runs at synchronous speed.
