Rated 4 with 7 reviewsThe R911277398 (MKD090B-058-KG1-KN) is a synchronous Servo AC motor from the Rexroth Indramat MKD Series. With a 24 VDC holding brake and electronic commutation, it runs at peak performance with both surface and natural cooling. It operates at a rated speed of 4000 rpm with a voltage constant of 70 V/1000min-1. This 4-pole motor has an initial shaft break-away needing a peak current of 79.0 amperes. It produces a continuous standstill torque of 12.0 N-m at 17.2 amperes. In natural cooling mode, it carries a rated torque of 8.9 N-m and a rated current of 9.2 amperes. Its maximum torque is 12 N-m with optional surface cooling. The brake pulls 0.71 amperes of current at 24 VDC, weighs 1.1 kg, and has clamping and release delays of 13 and 30 microseconds respectively. It comes with pre-greased bearings rated for 30,000 operating hours and a motor encoder for speed and position data.
