highest rpm Angle Grinder RP-MT954

Angle grinder can be divided into two categories, one is the brush Angle grinder, that is, the conventional model. One is a brushless Angle grinder, which is more advanced.
Structural distinction
Brush Angle grinder has two carbon brushes at the rotor, the carbon brush is the device that transfers energy between the fixed part of the Angle grinder and the rotating part, the main role is to conduct electricity while the metal friction, when the motor rotates, the electric energy is transmitted to the coil through the commutator, so as to complete the operation of the Angle grinder.
The brushless Angle grinder removes the carbon brush part, and uses magnetic force to drive the Angle mill to run, so there is no friction between the carbon brush and the motor, and the speed is lower, the speed is higher, and the power is greater.
In addition, the brushless Angle mill does not need to use carbon brush consumables, which saves the power consumption and friction resistance generated by the friction between the carbon brush and the copper head, which can save supplies and reduce production costs.
Appearance distinction
Motor appearance
The motor of the brushless Angle mill is smaller and has a rounded shape, while the motor of the brush Angle mill is larger and has a more square shape.
Body weight
Due to the small size of the motor, the entire body is usually lighter than the brush Angle mill.
Difference in use mode
Boot mode
The brush Angle mill usually uses a mechanical switch, and the brushless Angle mill mostly uses an electronic switch, which is more convenient to start.
Noise
The brushless Angle grinder produces less noise because the motor runs more smoothly.
Battery life
Brushless Angle grinders provide longer battery life due to higher motor efficiency.
Maintenance difference
Step 1 Change your brush
Brush Angle mills require regular replacement of motor brushes, brushless Angle mills have no such maintenance needs.
Replace the battery
Brushless Angle grinders require regular battery replacement, while brush Angle grinders do not.
Step 3: Clean
The motor design of brushless Angle grinders is more sophisticated and therefore requires more attention to cleaning and protection.
Selection suggestion
Although the price of brushless Angle grinders is higher than that of brushless Angle grinders, in the long run, the maintenance cost of brushless Angle grinders is lower because there is no need to replace the carbon brush regularly.
