Kollmorgen GOLDLINE BH/MH Servomotors continue the Kollmorgen tradition of high performance motors.
Designed around the classic, industry-standard Kollmorgen GOLDLINE series, the BH/MH motors are built with the highest-energy rare earth motors available.
Featuring the highest energy rare-earth NdFeB magnets and superior heat dissipation design, they provide excellent sustained and peak torque performance in a compact package.
The servo motors utilise patented IPM (Internal Permanent Magnet) design technology to achieve excellent torque-to-inertia and torque-per-volume ratios.
The BH/MH series servomotors are available in 5 frame sizes with 3 stack lengths per frame, and the BH/MH series has multiple windings per stack to meet a wide range of applications.
BH Series (Low Inertia)
The BH series has an extremely low rotor inertia for optimum performance in applications requiring rapid acceleration and deceleration.The IPM magnetic design provides extremely high torque density and torque/inertia ratio.
When coupled with SERVOSTAR®600 series amplifiers, the speed/torque range is the widest in the industry.
MH Series (Medium Inertia)
The MH series is an extension of the BH series. With seven times the inertia of the BH series, this series of motors offers superior performance for systems with compatible loads or large inertia mismatches.

Motor Ratings
Motor performance depends on the heat dissipation capability of the motor package. The ratings on the following pages assume that the motor is mounted on a metal mounting bracket capable of dissipating heat.
The ratings assume the following:
a.) For BH12x and BH22x: Continuous duty ratings apply to motors mounted on 96 sq. in. 1/4 in. thick aluminum panels.
b.) For BH42x, BH62x, and BH82x: Continuous load ratings are for motors mounted on 452 square inch 1’ thick aluminium panels.
c.) Equivalent thermal mass and radiant surface area are common parts of conventional machine designs. Other applications require derating.
