Working
It works on energy conversion system where a MG set with conventional 415V, 50Hz, 3ph input, and a output of 200V, 300Hz is achieved. This output is fed to the hand held power tool.
- Virtually no loss of rated power during full load grinding
- High efficient output
- Continuously constant torque
- More simpler and stronger construction of the motor
- No armatures, field coil, carbon brushes and no maintenance
- Low operating and energy cost
- Motor consist of stator and rotor, rotor is squirrel cage and stator has winding which is stationary so no rotating winding in the motor
- Speed drop is between 3 to 5% so higher cutting speed and 30% more productivity
- No fear for theft as it cannot run without suitable convertor
