Product Description:
The MSK071D-0300-NN-M3-UP1-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It converts electrical input into controlled rotary motion for positioning axes in automated machinery such as packaging systems, handling units, and transfer stations. This model uses frame size 071, length D, and winding code 0300, and its standard mechanical layout supports direct integration into compact motion assemblies. The motor’s synchronous design supports quick response to changing command values and helps maintain accurate motion in indexing and servo feed applications.
Heat is removed by natural convection, so the housing must remain unobstructed to support free air circulation around the motor surface. The enclosure carries an IP65 protection rating, which keeps out dust and resists low-pressure water jets commonly found in industrial areas. Position feedback is delivered through a capacitive encoder that communicates over the Hiperface interface, enabling digital synchronization with compatible drive controllers. The encoder plug is rotatable through 240°, which allows the cable outlet to be aligned to the available machine space without placing strain on the connector. Internally, the encoder produces 16 signal periods, and the drive can interpolate that signal for precise closed-loop position control. Because feedback and power functions are integrated in a compact housing, the motor fits installations where mounting space and cable routing are limited.
An electrically released holding brake supplies 23 Nm of static torque, securing vertical or overhung loads when the motor is de-energized. Continuous operation is permitted within an ambient temperature range of 0–40 °C, which suits typical indoor automation environments. Insulation class 155 supports winding durability during cyclic duty and elevated thermal loading. Mechanical power is transmitted through a shaft with keyway, providing a positive connection for couplings and pulleys where slip must be avoided. The combination of a holding brake and keyed shaft is suited to axes that must remain in place at standstill and transmit torque reliably during acceleration.
