Product Description:

Manufactured by Bosch Rexroth Indramat the MSK050С-0450-NN-M1-U-G0-NNNN Synchronous Motor exists as one of their industrial automation products. This motor features design capabilities for torque control while maintaining steady motion outputs. This motor reaches its maximum torque level at 15 Nm when operating at its peak.

The maximum current rating of the MSK050С-0450-NN-M1-U-G0-NNNN motor reaches 18.8 A. The torque constant stands at 1.16 Nm against each ampere applied to the device. A direct relationship exists between the current input and torque output. The motor winding withstands resistive forces equal to 3.2 Ohm. The wound inductance value stands at 20.2 mH. The stated parameters determine the manner in which the motor functions during load changes. The MSK050С-0450-NN-M1-U-G0-NNNN motor contains four pole pairs as part of its design. The exact motor control during synchronous rotation is supported through this design feature. A rotor with a moment of inertia measurement of 0.00033 kgm² exists within the unit. A quick direction change capability and reduced energy loss occur with this setup. The thermal time constant for this unit reaches 14.0 minutes during operation. The device generates sound below 75 dB(A).

The voltage constant of MSK050С-0450-NN-M1-U-G0-NNNN motor generates 71.5 V every 1000 min⁻¹. The unit speed generates a specific value of voltage. The motor falls under thermal class 155 according to EN 60034-1 standard. Standard operating conditions will receive protection due to this feature. The motor's protection rating achieves a level of IP65. Operation is feasible within an ambient temperature scale of 0 to 40 °C. The measurement of leakage capacitance shows a value of 2.4 nF. The electrical load variations do not impact the insulation quality. The motor flange meets the requirements defined by DIN 42948.
