Lifting Brush

The Master line motors stand out for the flexibility of their electrical and mechanical design, resulting in a high-performance product, complying with the international standards and aligned with the global trends.

Their design is easily customized so as to make them interchangeable with already existing motors, cutting down operating costs with downtime for motor replacement.

Wound rotor induction motors are recommended for reduction of the impact if inrush current in relation to the electrical system and driving loads with high inertia or high resistant torque.

Advantages:

Motorized brush lifting implies important advantages in the performance of the motor throughout the years:

Avoids constant and premature wearing of the brushes and collector rings

Reduce the stop for maintenance ad replacement of brushes

Avoids the accumulation of dust on the brushes inside the brush compartment to keeping the insulation level of the rotor high

Increase the useful life of the brushes, collector ring and consequently that of the motor
