maxon motor has expanded the company’s range of brushed DC motors with the new RE 65 power package delivers 250W which is designed to cope with the toughest demands. |
|
The motor is suitable for applications where high efficiency, high power density and a minimal operating noise are crucial.
As with all maxon motor's mechanically commutated drives, the heart of the RE 65 is the ironless rotor. The drive works detent-free and has minimal rotor inertia. High torques and 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 65mm diameter and 130mm length, delivers nominal torque of 0.5 to 0.9Nm - at a nominal speed of 2,400 - 3,700rpm. The power density is therefore more than double compared to existing drives. The RE65 can reach efficiency levels of up to 90 percent. Combined with low nominal voltages in the 18 - 70V range, the motor is ideally suited for battery-powered use, such as in electrical vehicles, transport and logistics equipment and mobile robots.
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. Accordingly, the new drive is also suitable for all kinds of applications in automation, engineering or medical technology.
