Product Description

The Bosch Rexroth MSK050C-0300-NN-M2-UP0-RNNN is a synchronous servomotor with maximum speed of 4300 RPM. The motor product line is MSK. According to the product type code, the motor frame size is 050 and motor length is C. The continuous torque at standstill (60 K) is 3 Nm. The continuous current at standstill (60 K) is 1.8 Amps. The continuous torque at standstill (100 K) is 3.4 Nm. The continuous current at standstill (100 K) is 2.0 Amps. The maximum current is the permissible phase current of the motor winding that does not adversely affect the magnet on the motor. The maximum motor current value is 7.2 Amps. The maximum torque is the motor torque at maximum current and depends on the drive control unit. the maximum motor torque value is 9 Nm. The motor torque constant at 20 degrees Celsius is 1.8 Nm/A.

The motor voltage constant at 20 degrees Celsius is 111 V/1000 RPM. The MSK050C-0300-NN-M2-UP0-RNNN motor includes an optical multiturn absolute encoder with 2048 signal periods. The shaft includes a keyway and a sealing ring. A holding brake is not available but can be ordered if required. The motor is designed with increased run out and concentricity. The housing is painted black. Ingress protection rating of the motor is IP65. This rating indicates robust protection from solids and liquids. The seal on the motor shaft also prevents oil leakages and dust/moisture ingress. The power and feedback connectors on the MSK050C-0300-NN-M2-UP0-RNNN motor can be rotated by 240 degrees. Cooling method for which the motor is designed is natural convection. The cooling can be improved by using forced air cooling. Approximate weight of the MSK050C-0300-NN-M2-UP0-RNNN servomotor is 4 kilograms.
