Brushed DC motor

The top performance range of maxon motor’s RE program is being boosted with the RE 65 delivering 250 W.

The motor is particularly suitable for applications where high efficiency, high power density and a minimal operating noise are crucial.

The heat of the motor is the ironless rotor. This means that the drive works detent free and has minimal rotor inertia. High torques and quick acceleration times are produced in combination with the 4-pole structure of the neodymium permanent magnets.

Depending on the winding variation, the cylindrical drive, at 65 mm diameter and 130 mm length, delivers nominal torque of 0.5 to 0.9 Nm — at a nominal speed of 2400-3700 rpm. The power density is more than double existing drives.

The motor can reach efficiency levels of up to 90%. Combined with low nominal voltages in the 18-70 range, it is suitable for battery-powered use, such as in electrical vehicles, transport and logistics equipment, mobile robots, etc.

Preloaded ball bearings support low-vibration and low-noise operation, offering the best conditions for a long service life in conjunction with graphite brushes. The modular system can provide matching planetary drives, encoders and controllers to suit every specific application for the RE 65.
