Avantages des moteurs synchrones perfectionnés dans les applications de chauffage, de refroidissement et de conditionnement d'air.

Advantages of enhanced synchronous motors in heating, refrigerating, and air-conditioning applications.

Résumé

A new synchronous motor is a high-efficiency alternating-current machine that has a low starting current. It may be used for conventional loads and also to start high inertia loads, delivering a constant torque during starting. Acceleration to synchronous speed can be allowed to take several minutes, if necessary, because the low starting current precludes excessive heating in the motor. Some of these motors are constructed with integral high inertia rotors that act as flywheels. These synchronous motors can "ride through" power sags and interruptions up to 30 seconds or more while still delivering useful load to pumps, fans, blowers, and compressors.
