Vacuum cleaner motors are series wound universal motors, powerful, and capable of extreme RPM's in excess of 10,000. A typical ceramic grinding wheel will fly apart around 5000 RPM and embed pieces in the wall, ceiling, and spectators. If it's got brushes, leave it in the junkpile. View attachment 89036.

The drive motor of the large ball mill is usually required to start with a reduced-voltage method . Therefore, the large ball mill usually uses air clutch to assist start-up. During the start-up process, the motor is started up to the rated speed. Then, the ball mill is started through the engagement of the clutch.

An induction motor is similar to a poly-phase transformer whose secondary is short circuited. Thus, at normal supply voltage, like in transformers, the initial current taken by the primary is very large for a short while. Unlike in DC motors, large current at starting is due to the absence of back emf.If an induction motor is directly switched on from the supply, it takes 5 to 7 times its …

In order to limit the starting current of the motor, star-delta starting can be used for grid fed induction machines. The induction machine is started in star connection and later switched to delta connection. This reduces the starting peak current to one third (see Figure 9). However, the starting torque is also reduced to one third.

A static phase converter uses motor start capacitors to start a 3 phase motor on single phase power. These capacitors are disconnected once the motor reaches full RPM. The motor continues to run on the 2 single phase lines of power. Two-thirds of the motor windings are being energized, producing approximately two-thirds of the motors power.
