Product Description:

The MSK100A-0450-NN-M1-AP1-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for precision motion control in automated machinery where coordinated speed and torque regulation are required to keep process variables tightly aligned with command profiles. Its synchronous design supports accurate positioning, repeatable cycle timing, and stable speed control in packaging equipment, transfer systems, and robotic handling axes. The integrated feedback and holding functions also reduce the need for separate external motion components around the axis.

This model uses natural convection for cooling, eliminating the need for forced-air or liquid circuits. The housing is sealed to IP65, which helps protect internal components from dust and water jets in typical industrial settings. Mechanical load holding is provided by an electrically released brake with 32 Nm of static torque, so the axis can remain stationary when power is removed. Power enters on the A side of the housing, and the shaft uses a keyway for positive drive coupling. The motor also has class 155 windings for controlled thermal performance during continuous operation. Feedback communication is handled through the Hiperface protocol, allowing position data and motor data to pass through the same interface to the drive.

The optical measurement system provides 128 signal periods per motor revolution, and its multiturn absolute capability tracks up to 4,096 mechanical turns without external batteries. Operation is specified between 0 and 40 °C, which suits typical indoor industrial climates. The stator uses winding code 0450, matching the electrical characteristics expected by compatible MSK drive inverters. Size 100 geometry with length code A gives the motor a compact profile for its torque class while keeping inertia suitable for responsive axis behavior. This layout supports repeatable motion on machines that require consistent starts, stops, and position recovery after brief interruptions.
