tendo®-PM: Permanent magnet motors and servomotors

High performance gears

Many DC gear motors are designed to reduce speeds, and are not suitable for the transmission of high torques. tendo®-PM motors reliably transmit every torque possible based on the motor output and gear transmission and run very quietly due to:

• Generous gear dimensions
• High tooth contact
• Low circumferential backlash
• Minimal gear tolerances

Fixed bearing with optimized ball bearing

The optimized fixed bearing with special grease filling on the A-side of the motor plays a major role in the good running and favorable noise characteristics of the motor. Many motor manufacturers do without fixed bearings and adapted grease filling, consciously risking unnecessary noises, harmful vibrations, and premature failure.

Optimally sealed The biggest problem with most DC motors is their open construction. They cannot be used in critical environmental influences. Here, too, tendo®-PM motors show their superior quality through:

• Protection IP54
• Protection IP65 (up to IP68 on request)

Very comfortable and extremely reliable through unique commutation

tendo®-PM motors feature a conspicuous commutation system with a generously dimensioned collector, a high number of collector lamellae, and large-area carbons with appropriately high wear volumes. This technical “luxury” provides the tendo®-PM with advantages which lift it substantially above the standard:
 

• Carbon service life ot 5000 to 6000 hours (2000 to 3000 hours are usual)
• Even running through low torque ripple and high speed constancy
• Extremely low-noise
