Product Description

MHD071B-061-PG1-UN is a servo motor. It is made by Bosch Rexroth for industrial applications. The motor is known as a servo motor because it supports feedback and forms part of a closed loop control system. The motor is controlled by a motor controller that supplies electrical power and controls motor speed and positon. Open loop control does not incorporate feedback. Closed loop control utilizes feedback for accurate motor speed and position control. The MHD071B-061-PG1-UN motor supports digital servo feedback. It is also equipped with an additional multiturn absolute encoder. It supports two cooling modes: surface cooling and convection cooling. Convection cooling relies on movement of ambient air over the operating servo motor. It is a cost effective method for motor cooling. Surface cooling utilizes a cooling fan to increase airflow over the operating servo motor.

Surface cooling requires additional capital expenditure, but enables delivery of higher output torque and current. Liquid cooling option is also available for MHD motors and offers the highest rate of heat dissipation. With convection cooling, the rated speed of the MHD071B-061-PG1-UN motor is 4000 RPM, the rated torque is 1.7 Nm and the rated current is 1.8 Amps. With surface cooling, the rated motor speed is 5000 RPM, the rated torque is 7.8 Nm and the rated current is 7.7 Amps. The maximum speed rating of the motor is 6000 RPM. Mass of the servo motor is 8.8 kilograms. It has an IP65 rated housing that provides robust protection against dust and moisture ingress. Bosch recommends 0 to 40 degrees Celsius temperature and 0 to 1000 meters altitude for MHD motor operation. Housing of the motor is protected by a black prime coat.
