Understanding Indramat MSK Motors
What Are Indramat MSK Motors?
Indramat MSK motors, now manufactured under the Bosch Rexroth IndraDyn S series, are high-performance synchronous motors known for their precision, compactness, and durability. These motors are widely used in demanding industrial applications, particularly where high torque, accurate positioning, and fast acceleration are required.
With IP65-rated protection, enhanced encoder systems, and optional holding brakes, MSK motors are engineered for efficient operation in harsh environments. The motors are available with plain or keyway output shafts, and each unit includes a data memory encoder that stores critical motor specifications.
Key Features of MSK Motors
-
Compact Design – Ideal for space-limited installations
-
High Torque Density – Delivers maximum power relative to size
-
High Dynamics – Quick acceleration and deceleration for precise motion control
-
Revised Optical Encoders – Enhanced position feedback for better accuracy
-
Built-In Temperature Monitoring – Includes a KTY84 sensor for thermal protection
-
Flexible Mounting Options – Suitable for horizontal or vertical mounting
Typical Applications
Indramat MSK motors are used across a wide range of industries due to their performance and adaptability:
-
Metal forming machine tools
-
Printing and packaging equipment
-
Paper processing lines
-
Food and beverage machinery
-
General automation requiring precise torque and speed control
Proper Handling and Installation Guidelines
Before operation, MSK motors must be inspected to ensure they are not damaged, not exposed to excessive temperature fluctuations, and clean from debris. Important installation and storage guidelines include:
-
Store horizontally in a dry, vibration-free, corrosion-protected area
-
Remove protective sleeves only prior to installation
-
Install vertically or horizontally, depending on machine requirements
-
Avoid exceeding ambient temperature limits (see below)

Frequently Asked Questions (FAQs)
What causes the MSK motor to shut down due to temperature?
The built-in KTY84 sensor monitors the stator temperature. If it reaches 150°C, the motor automatically shuts down to protect internal components.
What does the motor’s encoder memory store?
The encoder memory holds the type designation and configuration parameters, enabling automatic drive recognition and fast commissioning.
Can MSK motors operate above 3000 meters elevation?
No. Operation above 3000 meters is not recommended due to cooling and performance limitations. Performance may degrade and temperature regulation can be compromised.
What is the purpose of the housing’s black coating?
The RAL9005 epoxy-polyamide resin coating protects the housing from moisture, corrosive substances, and mechanical wear, extending the life of the motor.
