Product Description:
The MSK070E-0450-NN-S2-UG0-RNNN is a synchronous servo motor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a closed-loop drive element, it converts drive current into controllable torque and speed for positioning tables, handling modules, and similar automation axes. The motor integrates with IndraDrive controllers for tight velocity loops and rapid transient response. This operating principle supports accurate positioning and repeatable speed control during dynamic machine cycles. Its compact 070 frame supports installation in multi-axis gantries and packaging machines while maintaining high power density.
Heat is removed by natural convection, so the housing relies on surface area and ambient airflow rather than auxiliary fans. The rotor is ground to support increased concentricity, which helps reduce radial runout and supports coupling life. Position feedback is provided by a single-turn encoder that communicates over EnDat2.1. The optical grating delivers 2048 signal periods per mechanical revolution, supplying finely interpolated angle data to the drive. Because the sensing method is optical, the encoder provides stable digital feedback without contact wear. The motor is supplied without a holding brake, which helps keep rotor inertia lower.
A cast aluminum enclosure with IP65 protection is dust-tight and resists water jets, allowing direct mounting on processing equipment. The hardened plain shaft accepts clamp or taper couplings without a keyway, supporting backlash-free torque transfer. Continuous duty is permitted at ambient temperatures from 0 to 40 °C. Class 155 insulation allows higher winding temperatures before thermal aging becomes a concern under cyclic loads. Size 070, length E, and winding code 0450 indicate the mechanical stack and electrical impedance, while the 240° rotatable connector eases cable routing in tight cabinets. The connector position can also be adjusted to route cables around nearby machine structures.
