MKD041B-144-KG1-KN
MKD Synchronous Motors
The MKD041B-144-KG1-KN, manufactured by Bosch Rexroth Indramat, is part of the MKD Synchronous Motors series. This compact yet powerful servo motor incorporates a plain shaft and a robust IP65 housing to withstand harsh industrial environments. It features an integrated holding brake with a 2.2 Nm holding torque for positive load retention. Insulation class F and natural cooling ensure thermal resilience across continuous operation.
Designed to deliver precision motion, the motor supports a maximum speed of 7500 rpm and a continuous standstill torque of 2.7 Nm. Peak performance is assured by a 34 A peak current rating and a winding resistance of 1.8 ohms. Position feedback is provided by a resolver feedback with integrated encoder, offering absolute position detection over more than 4096 revolutions. The motor’s flange size of 82 mm and side B connection direction simplify mechanical integration, while the compact motor length code B optimizes cabinet space.
Engineers will appreciate the motor’s low rotor inertia of 1.7 x 10^-4 kgm^2, which enables rapid acceleration and deceleration for high-speed automation tasks. The sealed IP65 protection rating and integrated shaft seal guard internal components against dust and low-pressure water jets, enhancing long-term reliability. With its proven performance in demanding applications and facile mounting geometry, the MKD041B-144-KG1-KN is ideally suited for pick-and-place systems, rotary indexing tables, and other precision-driven industrial automation solutions.
