Brushless Hammer And Brush Hammer Comparison

There are differences between Brushless Hammer And Brush Hammer.

1. service life: the service life of the motor without carbon brush hammer is usually in the order of tens of thousands of hours. The continuous working life of the motor with carbon brush hammer is in the hundreds to more than one thousand hours. When it reaches the limit of use, it needs to replace the carbon brush, otherwise it is easy to wear the bearing, and the service life is not as good as the brushless motor.

2. maintenance cost: there is a carbon brush hammer need to replace the carbon brush, if the replacement is less than will cause damage to the motor, and no carbon brush hammer service life is very long, but the broken need to replace the motor, but the basic daily maintenance does not need.

3. controllability: no carbon brush hammer is usually controlled by digital frequency conversion, with carbon brush hammer generally start after the working speed is constant.

Extended information

The rotor of the motor acts as a rotating magnet. If the brushes are too worn, the excitation current cannot reach the rotor, there is no rotating magnetic field, and therefore it cannot operate properly. The mechanical friction and large current between the brush and the collector ring generate a lot of heat. At the same time, the collector ring device is limited by the shafting condition and the cooling mode, and the cooling condition is relatively poor. The heat on the collector ring device is relatively concentrated and the temperature is relatively high.

Brushless DC motor is a typical mechatronics product, which is composed of motor body and driver. A magnetized permanent magnet is glued to the rotor of the motor. In order to detect the polarity of the motor rotor, a position sensor is installed in the motor. The driver is composed of power electronic devices and integrated circuits.
