Product Description

The Bosch Rexroth MHD071B-061-NP3-UN is a MHD series synchronous motor. It has a frame size of 71 which corresponds to 115 millimeters flange size and 95 millimeters centering diameter. The motor frame length of B corresponds to continuous torque at standstill of 8.0 Nm. The MHD071B-061-NP3-UN is equipped with an integrated encoder system for digital servo feedback which provides relative position detection. The motor shaft is connected to machine elements that need to be driven. For this purpose, the MHD071B-061-NP3-UN comes with a motor shaft with keyway and shaft sealing ring.  A holding brake, which is required for clamping the servo axis when the machine is in the de-energized state, is also available. The holding torque of the brake is 10 Nm, and it is rated for 24 Volts DC and 0.65 Amps.

The brake has 10.7 x 10^-4 kg m² moment of inertia, 26 milliseconds connection time, 43 milliseconds disconnection time and its weight is 0.7 kilograms. Connector for electrical power on the MHD071B-061-NP3-UN is 270 degrees rotatable. For storage and transportation, Bosch recommends ambient temperature range of -20 to 80 degrees Celsius for the motor. For situations when the motor is operating under load, the recommended ambient temperature range is from 0 to 40 degrees Celsius. The MHD071B-061-NP3-UN is designed for surface cooling and natural convection. Environmental protection rating for the servomotor is IP65. The insulation class is F according to DIN VDA 0530 Part 1. For optimal operation, Bosch recommends that the motor be installed at altitudes that are less than or equal to 3280 feet. To achieve long term reliable operation, the installation and commissioning should be performed by experienced personnel. The MHD071B-061-NP3-UN can be shipped to any address globally with a one-year warranty period from Wake Industrial.
