The top performance range of maxon motor’s RE program is being boosted. The new RE 65 power package delivers 250 watts. The motor is particularly suitable for applications where high efficiency, high power density and a minimal operating noise are crucial, according to the company. The heart of the RE 65 is the ironless rotor. This means that the drive works detent-free and has minimal rotor inertia. High torques and very quick acceleration times are produced in combination with the four-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 2,400-3,700 rpm. The power density, therefore, is more than double compared to existing drives. The RE 65 can reach efficiency levels of up to 90%. Combined with low nominal voltages in the 18-70 V range, the motor is ideally suited 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. Maxon’s established modular system can provide matching planetary drives, encoders and controllers to suit every specific application for the RE 65.
