Product Description

SR-A1.0012.060-00.000 is a high-performance SR series servo motor from Bosch Rexroth. SR motors feature permanent magnets and electronic commutation. Electronic commutation is used to control the direction and flow of current in the windings of a brushless motor, with electronic switches instead of mechanical brushes. In motors that use electronic commutation, the switching of current in the windings is managed by an electronic controller, allowing the motor to run efficiently without the need for physical contact to reverse the current. The absence of brushes leads to less mechanical wear and tear, leading to increased motor lifespan and reduced maintenance requirements. SR motors are equipped with a resolver for feedback. They must be installed in combination with a Bosch Servodyn-D inverter. SR series motors feature an electronic rating plate for optimization of the inverter to the connected motor.

Nominal speed rating of the SR-A1.0012.060-00.000 motor is 6000 RPM. Performance data for the motor includes 1.2 Nm locked-rotor torque, 1.9 Amps locked-rotor current, 0.65 Nm/A torque constant, and 0.63 kg m2 rotor moment of inertia. Size of the mounting flange of the SR-A1.0012.060-00.000 motor is 70 millimeters. The motor shaft includes a keyway and feather key. Diameter of the shaft is 11 millimeters and its length is 23 millimeters. Length of the servo motor is 176 millimeters. Approximate weight of the motor is 1.9 kilograms. Ambient conditions recommended for SR motor operation include 0 to 40 degrees Celsius ambient temperature and 0 to 1000 meters site elevation. Performance of the motor derates outside these limits. The motor housing complies with IP67 requirements, providing extremely robust ingress protection for safe and reliable motor operation in different environments.
