High Speed 500W Brushless ER11 Spindle Motor + 55mm Clamp Bracket + Power Supply + Driver for CNC Router Machine Tool ,Efficient Performance

1. No brush & low interference The most direct change is that there is no spark from brush motor it greatly reduces the interference of the spark to the remote control radio. 2. Low noise & smooth operationThe friction is reduced during work run smoothly, and the noise is lower. It is a huge support for the stability of equipment operation. 3. Long service life & low maintenance cost The wear of the brushless motor is mainly on the bearing From a mechanical point of view, the brushless motor is almost a maintenance-free motor, it just need some dust removal maintenance. 4.Dielectric strength: 400V 5.Collet: ER11
