DC motor with compact right angle gearbox

When a compact solution is required for right angle transmission a spiroid gear is used instead of a worm gearhead. The spiroid gear offers a smaller profile than the traditional worm and wheel gearbox body. This unit consists of a 35mm brushed DC motor with and ironless rotor design that features zero cogging for smooth motion control. 105mNm of torque can be produced at 6990rpm on a 24V power supply. This is then passed through a 32mm 111:1 ceramic planetary gearhead giving 8.2Nm available which is then fed to a 4.125:1 spiroid gear with 90% efficiency. The gearhead has traditional tapped mounting holes on the front flange and also a convenient new off centreline pivot point for use in lifting actuators or for belt tensioning. The right angle drive has a robust machined construction and can be used with higher reduction ratios and with or without the intermediate planetary gear. There are a wide range of brushed and brushless motors with or without encoders. This unit depicted shows a 500cpt 3 channel optical encoder, however smaller magnetic encoders are also possible. For operation in tight spaces such as downhole oil, gas and pipe inspection robotics. For more information contact maxon motor Australia tel. +61 2 9457 7477.
