Coaxial Drive KD 32 - Silent & Powerful for DC motors

Supplier: maxon motor australia

New improved low-noise planetary gearhead for maxon DC motors, servo motors and Brushless DC motors.

Price Guide: POA

This new product is very hard to hear! The low noise coaxial-drive (Koaxdrive) KD 32 Planetary gearhead from maxon motor is setting new standards in operation noise and torque levels. Measuring 32 mm in diameter and with a torque of 6.5 Nm, it is ideal for use in noise-sensitive, highly demanding, servo motor applications.

The new high torque gearhead combines the best of two proven gearing technologies, namely worm and planetary gearing. Special attention has been focused on the first gear stage, as this is where the greatest peripheral motor speeds occur and therefore noise. Our completely new, patent protected design has enabled us to substantially reduce this noise. The worm-formed DC motor pinion drives the three offset planetary wheels. These interlock with the internal gear which has straight cut teeth. The planetary wheels are largely responsible for reducing noise levels.

All additional stages are set out as a completely 'normal" straight-cut planetary gearhead. This unique torque conversion makes servo operations very quiet - even with high loads.

With an outer diameter of only 32 mm and a coaxial arrangement on the drive and output shaft, the Koaxdrive is designed for compact automation applications. A number of efficiency levels with the same reduction ratio increases the wide variety of servo applications: in the 11:1 to 1091:1 range, many reduction ratios are available as standard. maxon motor also offers high reduction ratios in one stage.

A new, innovative coupling element is assembled on the DC motor or servomotor side so that the motor shaft is not subjected to axial load. Maximum flexibility is created by the motor shaft diameter not being of primary importance. High brushless motor input speeds of up to 8,000 RPM can easily be reached.

maxon's DC motor modular system enables the Koaxdrive KD 32 to be assembled with the various maxon motor options. These low -noise combinations are ideal for hand tools and instruments that are used principally on or near patients in the medical technology sector.
