Product Description

The Bosch Rexroth MSK070D-0450-NN-M3-UG1-NNNN is a synchronous servo motor. At 60K overtemperature, its continuous torque at standstill is 17.5 Nm and continuous current at standstill is 16.6 Amps. At 100K overtemperature, its continuous torque at standstill is 20 Nm and continuous current at standstill is 22 Amps. The motor is designed for cooling through natural convection. It can also be cooled via forced air cooling (surface cooling). When forced air cooling is employed, the continuous torque at standstill is 26.3 Nm and continuous current at standstill is 24.9 Amps. Maximum torque rating of the motor is 52.5 Nm and the maximum current rating is 49.8 Amps. The MSK070D-0450-NN-M3-UG1-NNNN motor has six pole pairs. The moment of inertia of the motor rotor is 0.00375 kg m². The motor thermal time constant is 23 Nm.

Peak speed of the motor is 6000 RPM. The average sound produced by an operating MSK070D-0450-NN-M3-UG1-NNNN motor does not exceed 75 dB. Combined weight of the motor and the integrated holding brake is 15.6 kilograms. The ideal ambient temperature range is 0 to 40 degrees Celsius. The ideal altitude of the installation side is 0 to 1000 meters. Motor operation outside these recommended ranges leads to derating of the output current. The main shaft on the MSK070D-0450-NN-M3-UG1-NNNN motor is plain and is fitted with a sealing ring. The built-in encoder is a capacitive multiturn encoder with 16 signal periods. The power and feedback connectors are rotatable. The holding torque rating of the holding brake on the MSK070D-0450-NN-M3-UG1-NNNN is 23 Nm. The motor housing has a standard design. Protection class of the motor is IP65 and the motor is completely protected from dust.
