مصنع لتجهيز البوكسيت/Synchronous Motors With Clutches For Mill
The AC Synchronous motor is an effective way to obtain a fixed speed at a very low motor system cost. No expensive driver or amplifier is necessary. Most synchronous motors are used where precise timing and constant speed are required. AC Synchronous Motors range in size from subfractional horsepower to over 10,000 horsepower.
· What is synchronous motor and why it needs exciter? Sunday, May 8, 2016. SYNCHRONOUS: means "turns at a speed proportional to applied frequency independent of load". For this to occur, the magnetic field on the rotor must be powered separately from the stator magnetic field. As Hector pointed out the rotor field may result from permanent ( ...
The synchronous motor is a type of AC motor that runs at synchronous speed. The asynchronous motor is a type of AC motor that runs on speed less than the synchronous speed. It operates on the principle of magnetic interlocking between rotor and stator field. It operates on the principle of electromagnetic induction between stator and rotor.
A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line ...

mill drives (RMDs) offer the best solution. Three of the most common drive types for RMDs are low speed motors without a gearbox, high speed motors with a reduction gearbox, and variable speed drives (VSDs). No gearbox: The low speed motor is connected directly to the pinion. The rated speed is typically around 200 to 400 rpm. Synchronous ...
