Product Description:
The MSK101D-0300-NN-S3-BG0-NNNN servomotor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It is an IndraDyn S servomotor intended to deliver controlled torque and speed to automated machinery when paired with an IndraDrive inverter. By combining sealed motor construction with integrated feedback, the unit supports precise axis control in packaging lines, machine tools, and material-handling gantries. Its operating role suits applications that require accurate positioning, repeatable motion, and stable speed control during frequent starts and stops.
Heat generated during load cycles is dissipated through natural convection, which allows installation without added cooling equipment. The enclosure carries an IP65 rating, so dust ingress and water jets do not compromise internal windings or bearings. Position feedback is delivered through a Hiperface interface that transmits absolute data from the integrated encoder, and its sensing principle is capacitive, which helps avoid magnetic interference. Within one mechanical revolution, the encoder produces 16 signal periods, allowing the drive controller to interpolate motion smoothly. Size code 101 and winding code 0300 identify the electromagnetic package, while length code D indicates the motor's active axial dimension and continuous torque range.
The encoder is a singleturn device, so absolute position is available for one revolution without multi-turn gearing. A plain shaft provides a smooth cylindrical interface for clamped or keyed couplings, and the power connector is oriented on the B-side for cleaner cable routing. The motor is supplied without a holding brake, so applications that require passive load holding need an external brake. Continuous operation is supported in ambient temperatures from 0–40 °C, and the Class 155 insulation system permits winding temperatures up to 155 °C. This insulation class supports the thermal load that can occur during repeated acceleration, deceleration, and holding cycles.
Frequently Asked Questions about MSK101D-0300-NN-S3-BG0-NNNN:
Q: How is the MSK101D-0300-NN-S3-BG0-NNNN motor cooled?
A: The MSK101D-0300-NN-S3-BG0-NNNN motor uses natural convection for cooling, operating without the need for forced air or liquid cooling systems.
Q: What type of shaft does the MSK101D-0300-NN-S3-BG0-NNNN motor use?
A: This model features a plain shaft, allowing for versatile coupling options and reduced mechanical complexity.
Q: What encoder interface is used on the MSK101D-0300-NN-S3-BG0-NNNN motor?
A: The encoder interface on this motor is Hiperface, providing advanced communication for position feedback.
Q: What is the protection rating of the MSK101D-0300-NN-S3-BG0-NNNN motor?
A: The MSK101D-0300-NN-S3-BG0-NNNN offers IP65 protection, which means it is dust-tight and protected against low-pressure water jets from any direction.
Q: Is the MSK101D-0300-NN-S3-BG0-NNNN equipped with a holding brake?
A: This model does not include a holding brake, so it will not provide built-in braking for stationary positions.
