Sinotech Motors
Custom AC Motorsis produced by the action of the rotor (secondary) currents on the air-gap flux. The synchronous motor differs greatly in design and operational characteristics, and is considered a separate class of ac motor. AC Induction Motors. AC induction motors are the simplest and most rugged electric motor and consist of two basic electrical assemblies: the wound stator and the rotor assembly. The AC induction motor derives its name from currents flowing in the secondary member (rotor) that are induced... (read more) -
Sinotech Motors
AC Linear MotorsThe first linear motor was conceived by Wheatstone more than 100 years ago. But large air gaps and low efficiencies prevented linear motors from being widely used. Though motors still have relatively large air gaps, linear induction motors are increasingly chosen for material-handling applications because they are quieter, more reliable, and less expensive than rotary electric motors. And because linear motors do not drive gearboxes or rotary-to-linear conversion devices, they can be more... (read more) -
