The R911261989 (MKD071B-061-KP1-KN) is a Bosch Rexroth servo motor engineered with a permanent-magnet rotor and electronic commutation, suitable for demanding automation applications requiring high acceleration and deceleration. Featuring a size 071 frame with a B motor length, the unit integrates a stator winding coded 061, four pole pairs, a 5 Nm holding brake, and a shaft with a keyway and sealing ring. The motor uses natural convection cooling and operates with a continuous standstill torque of 8 Nm at 11.2 A, achieving speeds up to 4500 min⁻¹. It provides absolute position feedback above 4096 revolutions, employs resolver feedback with an integrated encoder, and supports connection from side B. Mechanical specifications include a 95 mm centering diameter, 115 mm flange, 8.8 kg mass, and a housing finished in RAL 9005 black. The winding resistance is 1.45 Ω and the peak current capability is 50.4 A. Operational temperature range is -20 to +80°C.

Frequently Asked Questions

How is position maintained during power-off states in MKD071B-061-KP1-KN?

Stability on vertical or sloped axes is secured by a 5 Nm holding brake, preventing drift and keeping machinery safe during shutdowns.

What margin supports acceleration planning in MKD071B-061-KP1-KN?

This motor has theoretical maximum torque 32 Nm provides overhead for bursts, which improves safety during stops and starts with little effort.

What pilot diameter supports concentric assembly in MKD071B-061-KP1-KN?

This model has with 95 mm centering pilot reduces runout and vibration, protecting bearings, so heat stays low when loads change.

How does sealing support uptime in MKD071B-061-KP1-KN?

This model provides ip65 protection guards against dust and water jets for durable operation, to keep noise down every day.

What stall capability stabilizes fixtures in MKD071B-061-KP1-KN?

It weighs 67 kg. The higher mass damps vibration and lowers resonance amplitude, improving surface finish, path accuracy, and tool life in large frames or rigid automation cells.
