This product description pertains to Bosch Rexroth's R911306638 (MSK060B-0600-NN-S2-UG1-RNNN) Synchronous Motor. The device can be cooled naturally or through surface cooling. With surface cooling and the unit at standstill, it has a continuous torque of 10.4 Nm while the continuous current is absent. At 60K, the continuous current is approximately 9.5A and the torque is 8Nm. However, with 100K overtemperature and the unit at a standstill, the continuous torque is around 8.8 Nm and the continuous current is 10.5 Amps. When the temperature is maintained at 200C, the constant voltage is 57V/min-1, the torque constant is 0.93Nm/A, and the winding resistance is 0.8 Ohms. The motor's optimal operating temperature is 0 to 400C, with a thermal time constant of 14 minutes. The leakage capacitance is 2.2nF and the rotor moment of inertia without brakes is 0.0008KgXm2.
