Product Description
The Bosch Rexroth MHD071B-061-PG0-UP is a MHD series synchronous motor. The electrical parameters for motor for the 60 K overtemperature conditions are: 8 Nm continuous torque at standstill, 11.2 Amps continuous current at standstill, 50.5 Amps peak current, 4000 RPM rated speed, 1.7 Nm rated torque, 1.7 Amps rated current, 0.8 kilowatts output power, 283 Volts rated voltage and 267 Hertz rated frequency. The electrical parameters for motor for the 100 K overtemperature conditions are: 9 Nm continuous torque at standstill, 13.2 Amps continuous current at standstill, 50.5 Amps peak current, 5000 RPM rated speed, 5.3 Nm rated torque, 5.5 Amps rated current, 3.4 kilowatts output power, 368 Volts rated voltage and 333 Hertz rated frequency. The theoretical maximum torque of the MHD071B-061-PG0-UP motor is 32 Nm. The motor has 4 pole pairs.
Inductivity of the motor winding on the MHD071B-061-PG0-UP is 7.2 millihenry. The resistance of the motor winding at 20 degrees Celsius is 1.45 Ohms. The voltage constant at 20 degrees Celsius is 0.77 Nm/A. The rated maximum motor speed is 6000 RPM. The motor supports digital servo feedback with integrated multiturn absolute encoder. The housing of the MHD071B-061-PG0-UP is designed for natural convection or surface cooling. The shaft on the MHD071B-061-PG0-UP is plain and is fitted with a sealing ring. A holding brake, if required, has to be ordered separately as an option: brakes rated for 5 Nm, 6.5 Nm and 10 Nm holding torque are available. Sealing air connectors are available as an option for MHD motors such as the MHD071B-061-PG0-UP. These connectors are attached to the motor by replacing the flange socket cover, and protect the motor from penetrative oils, aggressive coolants and similar substances.
