Product Description

The Bosch Rexroth MSK070D-0300-NN-M1-BG0-NNAN is an advanced servo motor. It features a built-in encoder. The encoder is a multiturn device that is rated for 128 signal periods. The distinguishable revolutions for the encoder are 4096. The encoder accuracy is ±120 angular seconds. This encoder can measure maximum 9000 RPM motor speed. Current requirement of the encoder is 60 milliamps and the supply voltage range is 7 to 12 Volts DC. A total of six different types of encoders are available for MSK motors and can be ordered depending on customer requirements. The MSK070D-0300-NN-M1-BG0-NNAN motor does not include a holding brake. However an electrically-releasing brake is available from Bosch for MSK070D motors and can be specified at the time of ordering. The main shaft on the MSK070D-0300-NN-M1-BG0-NNAN is plain and is fitted with a seal.

MSK motors have rotatable power and feedback connectors. The MSK070D-0300-NN-M1-BG0-NNAN motor dissipates heat produced during operation through natural convection. MSK motors designed for surface cooling are also available. The permitted ambient temperature for motor operation is 0 to 40 degrees Celsius. Protection class of the MSK070D-0300-NN-M1-BG0-NNAN motor is IP65. The motor housing provides complete protection against dust. The motor housing also provides protection against low-pressure water jets. The thermal class of the MSK070D-0300-NN-M1-BG0-NNAN is 155. The maximum torque output of the motor is 52.5 Nm and the maximum current output is 33 Amps. The windings on the MSK070D-0300-NN-M1-BG0-NNAN motor have 0.75 Ohms resistance when measured at 20 degrees Celsius. The number of pole pairs on the motor are six. The thermal time constant is 23 minutes. Maximum speed of the motor is 4900 RPM and the average sound pressure produced during normal operation is less than 75 dB.
