R911321027
The Bosch Rexroth Indramat R911321027 (MSK070E-0300-NN-M2-UP1-RNNN) is a part of the MSK series of industrial synchronous motors, distinguished by its numerous features. These encompass a multiturn encoder with an EnDat 2.1 interface, rated for 2048 signal periods and affording up to 4096 revolutions, a holding brake with 23 Nm torque, along with rotatable connectors and a shaft furnished with a keyway. The encoder functions at a maximum speed of 12,000 RPM and records an accuracy of ±20 angular seconds, with a supply voltage range of 7 to 12 Volts DC. The shaft conforms to DIN 6885-1 standards with an attached sealing ring, and the brake operates at 24 Volts DC, drawing 0.79 Amps current.
Adhering to the standards of DIN 42955, the motor housing has been engineered for optimum concentricity and run out. Using natural convection, the motor cools with a functional temperature range of 0 to 40 degrees Celsius. Output derating occurs between 45 and 55 degrees Celsius. For ideal operation, the motor should be installed at an altitude of 0 to 1000 meters. A relative air humidity of between 5% and 95% is ideal for operation and a maximum change of 0.5 degrees Celsius per minute is the acceptable temperature alteration rate. A drive controller powers the motor and receives feedback through a separate feedback cable connected to a connector.
