Motor Generator set is a device used to convert electrical power to another form of energy (mostly AC to DC). It consists of a motor and a generator connected mechanically on the same shaft. The electrical supply is given to the motor. The mechanical output of a motor is used to rotate the generator. The type of generator depends on the applications. Normally change from 50Hz 60Hz into 100Hz 120Hz 150Hz 180Hz 200Hz 400Hz. We can produce as your need.

The applications of a motor-generator set are as listed below.
- The motor-generator set is used to remove transients in power supply.
- This set gives a smooth power cut from the main supply.
- It can be used instead of semiconductor devices for the same applications. This set can deal with large overloads for a short time compared to modern semiconductor devices.
Advantages & Disadvantages of M-G Set
Advantages
Following are the some advantages of a M-G set.
- It is a self-starting device.
- It can also be used as a power factor improvement device.
- It is reliable with a simple design.
- A wide range of DC voltage regulations can be achieved using the M-G set.
- There is no risk of rever se polarity and flash-over in the motor generator set.
- The DC output of the generator is constant and won’t be affected by the change in AC supply voltage to the motor. If the change in supply voltage to the motor and load connected to the generator is large enough, the process of synchronization may be lost.
- The DC output can be easily controlled by adjustment of the shunt field regulator.
- The synchronous motor can be directly connected to the supply voltage without installing a separate transformer (which is necessary in case of rotary converter).
