Product description
Designed as a permanent-magnet synchronous servo motor in the MKD071 range, the Bosch Rexroth MKD071B-061-KP1-KN handles controlled drive motion. Winding 061 provides 8 Nm continuous standstill torque and 11.2 A continuous current with natural convection; peak current is 50.4 A. Maximum speed is 6,000 min⁻¹. Code K identifies resolver feedback with an integrated multiturn absolute encoder. The output shaft is a keyed design according to DIN 6885-1 with a shaft sealing ring. The option sequence also includes a 24-V holding brake with 5 Nm holding torque. Power and encoder connections are routed through the terminal box, whose cable outlet can be aligned to side A or B during installation. Electrical characteristics include a torque constant of 0.77 Nm/A, a voltage constant of 70 V per 1,000 min⁻¹, 1.45 ohms winding resistance and 7.2 mH winding inductance. The rotor has four pole pairs and an inertia of 8.7 × 10⁻⁴ kgm². The thermal time constant with natural convection is 45 minutes. The permissible ambient temperature range is 0 to 40 °C. The standard housing is rated IP65 with insulation class F. Mechanical details include a 115 mm flange, 95 mm centring diameter and 19-mm shaft. Axial length is 264 mm.
