Product Description:
The MSK070C-0450-NN-S2-UP1-RNNN servomotor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop positioning and velocity control in assembly cells, packaging stations, and other axes where fast dynamic response is required. When paired with an IndraDrive power stage, it converts electrical input into controlled rotary motion for coordinated machine movements. This arrangement supports accurate acceleration, repeatable stopping behavior, and stable torque output during changing load conditions.
The motor relies on natural convection for heat removal, so surrounding airflow must allow the housing surface to dissipate losses without forced cooling hardware. Position feedback is provided through an optical encoder that communicates via the EnDat2.1 interface, and its scanning disk delivers 2048 signal periods per revolution for fine interpolation by the drive controller. The feedback connector is rotatable through 240°, which helps simplify cable routing in confined machine spaces. Environmental sealing meets IP65, helping protect internal components against dust and routine washdown exposure. The size 070 housing with C length and winding code 0450 gives the motor a balance of torque density and inertia that suits medium-duty servo applications.
Mechanical power is transferred through a shaft with a keyway, allowing direct coupling to pulleys or gearboxes without slip. An electrically released brake supplies 23 Nm of holding torque, which helps keep vertical loads in place when drive power is removed. Safe operation is permitted at ambient temperatures from 0 to 40 °C, and the windings use insulation class 155 for continuous-duty thermal resistance. Single-turn optical feedback and a balanced rotor support precise indexing and steady motion in transfer systems, gantry axes, and other automated equipment.
