A permanent magnet synchronous motor and reluctance motor requires a control system for operating (VFD or servo drive). There is a large number of control methods for synchronous machines, selected depending on the construction of the electric motor and the scope. Control methods can be divided into: [21] [22] Scalar control. V/f control ...
An automobile starter motor (larger cylinder). The smaller object on top is a starter solenoid which controls power to the starter motor and engages the Bendix drive.. A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power.

It is used to dampen the transient oscillations and facilitate the start-up operation. [ 2 ] Since the design of a damper winding is similar to that of a asynchronous motor , the winding technically enables the direct-on-line start and can even be used for the motor operation in the asynchronous mode.
The R required a starter motor, which was also a two-cylinder engine, horizontally-opposed, burning gasoline to warm up the prime engine. The pony engine had electric start. In addition to being the first Deere diesel tractor, the R was the first to have a "live" power take-off , with its own clutch allowing independent control of the PTO.
A separate motor (called pony motor) is used to drive the rotor before it locks in into synchronization. The field winding is shunted or induction motor like arrangements are made so that the synchronous motor starts as an induction motor and locks in to synchronization once it reaches speeds near its synchronous speed.
The Coffman engine starter (also known as a "shotgun starter") was a starting system used on many piston engines in aircraft and armored vehicles of the 1930s and 1940s. It used a cordite cartridge to move a piston, which cranked the engine.
Reduced starting current is desirable where the electrical grid is not of sufficient capacity, or where the driven load cannot withstand high starting torque. One basic method to reduce the starting current is with a reduced voltage autotransformer with taps at 50%, 65% and 80% of the applied line voltage; once the motor is started the ...
