Product Description:

The MSK070C-0300-NN-S1-UG0-NSNN synchronous servomotor is manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts electrical energy into precise rotational motion for positioning, feed, and tooling axes in packaging, machining, and material-handling equipment. The motor integrates high-resolution feedback for accurate speed and torque control when it is paired with a compatible Rexroth inverter, making it suitable for synchronized motion tasks that require repeatable positioning and responsive servo behavior.

The housing has an IP65 rating, which helps protect internal components from dust and low-pressure water spray on open machine installations. Heat is removed by natural convection, so no auxiliary fan is required and the motor can be used where simple cooling is preferred. Rotor position is measured by an optical sensing system that communicates through Hiperface, providing digital feedback to the controller. This arrangement supports closed-loop operation without separate external sensing hardware on the axis. Rated operation is maintained in an ambient temperature range of 0 to 40 °C.

The motor has a frame size of 070, which sets the mounting dimensions, and a length code of C, which gives it the corresponding stack length for this housing. It uses winding code 0300, matching the electrical values expected by compatible drive modules, and insulation class 155, which supports elevated winding temperatures during cyclic loading. A plain shaft supports direct coupling to clamping hubs, and the rotatable 240° encoder connector helps with cable routing in tight enclosures. The feedback system is single-turn with 128 signal periods for absolute position at power-up, and the motor is supplied without a holding brake. Because the shaft is plain and the brake is omitted, any holding function at standstill must be provided by the driven mechanism or the control system.
