Differences between Brushless Grinder and Ordinary Grinder

The motor part with carbon brush and commutator is called with brush. After being energized, the carbon brush and commutator work to generate magnetic field and convert it into kinetic energy. The brushless motor rotor section has magnets, so it is called brushless without carbon brushes, and the magnetic field is larger after being energized.

Brushless grinding machine with large torque, high efficiency, long service life and time saving

High torque: because the brushless motor has magnetic force, the magnetic force is greater after power on, while the ordinary grinder has no magnetic force, and the magnetic force and brushless motor have a lot of difference after power on, so the torque difference is here.

High efficiency of the brushless grinding machine: the high efficiency comes from the small speed drop of the brushless grinding machine when the starting and stopping no-load speeds are the same as those of the ordinary grinding machine. The speed drop of the ordinary grinding machine is large, and all the efficiency is high. Much better than ordinary grinder

Long service life of brushless grinder: the service life of ordinary grinder is limited by the wear of carbon brush and the aging of commutator, so the service life is short. Therefore, the service life of the brushless grinder is more than 3 times longer than that of the ordinary one. Do not burn after continuous working for a long time.

Load capacity: under heavy load conditions, the speed drop of the brushless grinder is smaller than that of the ordinary grinder. The speed drop comes from friction resistance, so the brushless grinder is better used. Under heavy load, it is like running a brushless grinder at high speed and a common grinder at low speed. Driving at high speed for the same mileage is less likely to waste tires.
