Brushed DC Motor delivers 250 W and reaches 90% efficiency.
Press Release Summary:
Constructed with ironless rotor and 4-pole structure of Neodymium permanent magnets, mechanically commutated RE65 works detent-free and has minimal rotor inertia. Preloaded ball bearings support low-vibration and low-noise operation, and nominal voltage is in 18-70 V range. Depending on winding variation, 65 mm dia x 130 mm long cylindrical drive delivers nominal torque of 0.5-0.9 Nm at nominal speed of 2,400-3,700 rpm.
Original Press Release:
Powerful DC Motor RE 65; maxon motor Expands its Range of Brushed DC Motors.
The top performance range of maxon motor's RE program is being boosted. The new RE 65 power package delivers 250 watts and can handle the toughest demands. The motor is particularly 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. 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 is therefore more than double compared to existing drives. The RE65 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. This new drive is ideally suited for all kinds of applications in automation, engineering or medical technology.
