MHD071B-061-NG3-UN

Product Description

The Bosch MHD071B-061-NG3-UN is a Rexroth MHD series synchronous servo motor. The motor frame size is 071: the motor flange size is 115 millimeters and the centering diameter is 95 millimeters. As per the type code the frame length is B and winding code is 061. The MHD071B-061-NG3-UN supports digital servo feedback. The motor has a plain motor shaft with a sealing ring. The function of the sealing ring is twofold: to prevent oil leakage and prevent ingress of external contaminants that could damage the bearings. The power connector on the MHD071B-061-NG3-UN can be rotated 270 degrees. The motor housing is designed for natural convection or surface cooling. The working temperature range is 0 to 40 degrees Celsius. The protection rating of the motor housing is IP65: the motor is protected from dust and low-pressure water jets.

The servo motor can be mounted outside cabinets and near the operating machines. An integrated holding brake rated for 10 Nm holding torque is available on the MHD071B-061-NG3-UN motor. The characteristic motor speed is 4500 RPM. The rated motor speed for the 60 K conditions is 4000 RPM. The rated motor speed for the 100 K conditions is 5000 RPM. Maximum speed of the MHD071B-061-NG3-UN motor is 6000 RPM. Weight of the MHD071B-061-NG3-UN is 8.8 kilograms. The maximum setup altitude for the servo motor is 1000 meters above sea level. The motor may only be put into operation if it has been properly mounted and the electrical connection has been properly established. It should be ensured that the rotor of the MHD071B-061-NG3-UN can be turned manually when the holding brake is open. The protective conductor / grounding should be connected properly before motor commissioning.
