Brushless Angle grinder and what is the difference between traditional Angle grinder

Angle grinder, after decades of evolution and development from the original large size, heavy, need two people together operating characteristics, development to today's small and light, power strong, single single hand operation, even a great progress. At the same time, the development of Angle grinder and the development of the industry all over the world play a huge role. As the change of The Times, the development of technology, brushless grinder are becoming more common, so brushless Angle grinder and what is the difference between traditional grinder? ( ) Without carbon brush and eliminate the effects of carbon brush powder on body for operators to dispense often replace carbon brush. Without carbon brush and copper head friction sparks, explosion-proof effect, also not interfere with the signal around the circuit. ( ) Switch the button type, energized again after work if there are any power outage, the machine will not start on its own, reduce the happening of the accident, use more secure. ( ) Work properly when the motor can keep the rated speed and make the work more efficiently, and at any time don't have to consider to replace carbon brush, also need not worry burn rotor, the use of more efficient. ( ) Brushless motor without carbon brush and copper head assembly friction power consumption and frictional resistance, generated by the power output ratio compared with the traditional Angle grinder % above. ( ) Motor rotor is made of high strength silicon steel sheet, and is not a traditional rotor coil winding way, never burn rotor. ( ) Motor speed slow start when the phone is switched on, won't produce a spin phenomenon, more comfortable to operate. And because it is a slow start, effectively reduce the moment of the motor starting current, more effective to extend the life span of the motor and related equipment. ( ) Besides bearing and gear to normal maintenance, the machine there is no other parts. To minimize the maintenance cost.
