Product Description

The MKD071B-061-PG1-UN is a highly efficient synchronous digital servomotor produced by the multibillion-dollar company Rexroth Bosch. Belonging under the MKD synchronous motor series, the MKD071B-061-PG1-UN has a proven track record for delivering powerful driving capabilities for machine tools, printing, automation, handling, and packaging applications. Most MKD motors are known for their reliability, maintenance-free operation, and effective overload protection devices. Like other MKD motors, the MKD071B-061-PG1-UN also offers easy installation, high dynamics, and continuous start-stop operation. It consists of a permanent magnet on its rotor, allowing it to rotate easily for rapid conversion of electricity to motion.

MKD motors such as the MKD071B-061-PG1-UN come in various types, sizes, and configurations. Specifically, the MKD071B-061-PG1-UN has a frame size of 071B, a 061-winding, and a smooth plain shaft. During operation, this motor can employ its standard holding brake to hold the rotor in place at a maximum torque of 22 Nm. For highly precise servo applications, the holding brake provides a mechanism to ensure that the rotor stays in one angular position. With its 071 frame, the MKD071B-061-PG1-UN has a flange size of 115 mm and a centering diameter of 95 mm. Motors with a 95 mm centering diameter are common for average industrial applications.

At standstill conditions, 071B motors like the MKD071B-061-PG1-UN can achieve a continuous torque of 8 Nm. With its P-type motor feedback, the MKD071B-061-PG1-UN employs resolver feedback with multiturn absolute encoder. Absolute encoders can detect the rotor’s position more accurately than relative or incremental encoders. With its type U power connector, the MKD071B-061-PG1-UN’s encoder and power connectors are turn-able within an angular range of 270 degrees. During operation, the MKD071B-061-PG1-UN can withstand a nominal ambient range of 0 to 40 degrees Celsius.

Frequently Asked Questions about MKD071B-061-PG1-UN


Q: What is the difference between 60K and 100K for MKD motors like the MKD071B-061-PG1-UN?

A: Synchronous motors under the MKD series line can either be a 60K or 100K motor. Motors under the 60K family have a permissible housing overtemperature of 60 Kelvin. Consequently, motors under the 100K product line have a higher permissible overtemperature of 100 Kelvin on their housing.

Q: What are the speed characteristics of the MKD071B-061-PG1-UN?

A: The MKD071B-061-PG1-UN has a characteristic speed of 4500 rpm, a rated speed of 4000 rpm (60 K) or 5000 rpm (100 K), and a maximum speed of 6000 rpm.

Q: What is the theoretical maximum torque of the MKD071B-061-PG1-UN?

A: The MKD071B-061-PG1-UN has a theoretical maximum torque of 32 Nm.

Q: How heavy is the MKD071B-061-PG1-UN?

A: The MKD071B-061-PG1-UN has a weight of 8.8 kilograms.

Q: What are the standstill values of the MKD071B-061-PG1-UN?

A: The MKD071B-061-PG1-UN achieves the following standstill values assuming a 60K classification: 8 Nm and 11.2 A. For a 100K classification, the MKD071B-061-PG1-UN achieves the following standstill values instead: 9 Nm and 13.2 A.

Internal Product Review

  • ‘‘Rexroth indramat’s MKD071B-061-PG1-UN is an impressive synchronous servomotor that comes with complete documentation. It achieves a relatively higher nominal speed and employs natural cooling to prevent motor overtemperature.’’
