Product Description:
The MSK076C-0300-NN-M1-UG0-NSNN servo motor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. With frame size 076 and length C, the unit fits medium-torque applications that require precise rotary motion. In industrial automation, it pairs with IndraDrive power stages to position tooling, index workpieces, or synchronize conveyor lanes through closed-loop motion control. Its 0300 winding balances current demand with torque density, which supports responsive acceleration and stable operation on repeat-cycle axes.
Cooling is handled by natural convection, so heat leaves the stator through the housing surface without fans or liquid lines. The motor is approved for standard installations and for areas that require explosion protection. Position feedback is provided through a Hiperface optical encoder that offers 128 signal periods per revolution, giving the drive the data it needs for commutation and motion control. Because the shaft is a plain shaft, the mechanical interface relies on external clamps or couplings rather than a keyway. A sealing system rated at IP65 blocks airborne particles and water jets from reaching internal laminations, and the motor is supplied without a holding brake, so loads must be secured externally when power is removed.
During installation, the encoder plug can be oriented with a rotatable through 240° connector, which helps route cables in compact machines. The encoder stores position data on a multiturn absolute scale, allowing the controller to recover angle information immediately after power cycles. Class 155 insulation allows the copper windings to withstand temperatures that match the passive cooling arrangement. Continuous service is specified for ambient air from 0 to 40 °C, which covers most assembly areas and keeps thermal rise within the motor's permissible limit.
