Product Description:
The MSK100B-0400-NN-S2-BP2-RNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for closed-loop positioning and velocity tasks in automated machinery. As a member of the MSK IndraDyn S Synchronous Motors series, the unit converts regulated three-phase drive current into mechanical torque so that axes in packaging, printing, or material-handling equipment can follow controller commands with repeatable accuracy. Its compact frame and integrated feedback allow direct mounting in multi-axis gantries without intermediate transmissions.
It relies on natural convection for heat dissipation, so airflow around the stator fins is sufficient during continuous duty without auxiliary fans. Position data is generated by an optical single-turn encoder that provides 2048 signal periods per revolution and communicates through the EnDat2.1 interface, allowing high-resolution feedback and digital diagnostics over a short serial link. A keyed steel shaft transmits torque, and the electrically released holding brake applies 70 Nm of static torque to secure vertical or suspended loads when power is removed. The housing has an IP65 rating, which indicates dust-tight sealing and resistance to low-pressure water jets. The power connector is on the B-side, and increased concentricity reduces radial runout during rotation.
The motor has a frame size of 100 and a length designation of B, which provide stator stack dimensions and inertia suited to medium-power axes. Thermal endurance comes from insulation class 155, supporting winding temperatures appropriate for cyclic servo operation. Reliable performance is maintained through an ambient temperature range of 0–40 °C, matching typical shop-floor conditions. These operating limits support stable use in enclosed industrial machines where accurate servo response is required.
