Bosch Rexroth MSK100B-0200 Synchronous Servo Motor
An IndraDyn S permanent-magnet synchronous servo motor base type with 28 Nm standstill torque and a 102 Nm maximum-torque class.
Key Information
MSK100B-0200 is a Bosch Rexroth IndraDyn S synchronous servo motor base type. The submitted string identifies the frame and winding but not the complete encoder, shaft, brake, cooling and connection execution.
The full nameplate code must control supply. Technical values below describe the MSK100B-0200 winding and basic motor; option-dependent dimensions, feedback and brake data require the complete designation.
Functions
- Provides dynamic permanent-magnet servo operation with the matching Rexroth drive and motor-feedback system.
- Supports natural cooling and the documented surface-cooling operating point where the complete execution permits it.
- Offers configurable encoder, shaft, holding-brake and connection options through the full MSK ordering code.
- Supplies a high peak-torque reserve for controlled acceleration and deceleration within the drive sizing limits.

Installation
- Use the complete motor code and drive project to verify encoder interface, power connector, brake supply and cable set.
- Size the axis from the application torque-speed cycle, cooling condition, altitude and thermal duty rather than peak torque alone.
- Preserve shaft alignment, coupling limits, protective earth and motor-cable shielding.
- After installation, verify feedback polarity, commutation, brake release, travel direction and drive limits before production motion.
Lifecycle
- Retain the full nameplate, Rexroth material number, motor serial number and drive parameter record.
- Do not treat another MSK100B winding as interchangeable; electrical constants and torque-speed behavior differ.
- Plan any IndraDyn migration as a motor-drive-cable-mechanics package.
FAQ
Is MSK100B-0200 a complete orderable motor code?
No. The suffix fields defining cooling, encoder, shaft, holding brake and connection execution are still required.
What drive information is needed for an MSK100B-0200 quotation?
Provide the IndraDrive type, DC-bus and supply arrangement, encoder interface, motor cable, brake supply and stored axis project.
Can MSK100B-0200 be exchanged with MSK100B-0300?
Not by frame size alone. The winding constants, current demand and torque-speed curves differ and require a new sizing and drive review.
When is the surface-cooled operating point relevant to MSK100B-0200?
Only when the complete motor execution and installed cooling arrangement meet the manufacturer’s conditions; it is not the default natural-cooling rating.
What mechanical checks are required before fitting MSK100B-0200?
Confirm shaft option, flange, pilot, coupling, brake, connector orientation, load inertia and mounting accuracy from the full code and drawing.
What should be tested after installing MSK100B-0200?
Verify encoder recognition, commutation, brake operation, direction, limits, thermal behavior and the complete machine safety sequence at controlled speed.
