MKD071B-061-GP0-KN

MKD071B-061-GP0-KN is a Bosch Rexroth Indramat servo motor in the MKD Synchronous Motors series. The motor is size 071 with length B and winding code 061. Its 115 mm flange and 95 mm centering diameter support alignment and mounting to compatible machinery. The connection box is directed toward side B to provide access for electrical wiring. The motor operates in ambient temperatures from 0-40ºC and has IP65 protection against dust and water jets. Its insulation class is F, and its mass is 8.8 kg.

The motor supplies 8.0 Nm of continuous torque at standstill and has a theoretical maximum torque of 32 Nm for peak-load operation. Its maximum speed is 6,000 min^-1. The peak current is 50.4 A, while the torque constant of 0.77 Nm/A indicates the torque produced per ampere. The voltage constant is 70 V per 1,000 min^-1. The winding has 7.2 mH of inductance and 1.45 Ω of resistance, which affect current response and electrical losses. Four pole pairs generate the motor’s rotating magnetic field. Rotor inertia is 8.7 × 10^-4 kg·m² and affects acceleration and deceleration response.

Resolver feedback provides relative position detection for motor commutation and motion control. System precision is ±8 angular minutes, indicating the accuracy of the detected shaft position. The shaft has a keyway for transferring torque to a keyed coupling or driven component, and the shaft seal helps prevent contaminants from entering around the shaft. The motor does not include a holding brake, so it does not mechanically retain the shaft position when power is removed.
