Product Description
SR-A3.0093.060-14.823 is a servo motor from Bosch Rexroth’s SR series. It is equipped with a resolver for feedback. A resolver is a type of rotary electrical transformer used to measure the motor's position and provide feedback to the control system. It is typically used in high-precision applications where knowing the exact position of the motor shaft is essential. Locked rotor torque of the motor is 9.1 Nm. Its rated speed is 6000 RPM. The locked rotor current is 13.5 Amps. Torque constant of the servo motor at 40 degrees Celsius is 0.67 Nm/A. moment of inertia of the rotor, including the encoder, is 16 kg m22. SR-A3.0093.060-14.823 is a flange-mounted motor and the flange size is 116 millimeters. Diameter of the motor shaft is 19 millimeters and its length is 40 millimeters. Length of the motor without the holding brake is 287 millimeters. Mass of the motor, excluding the brake, is 12 kilograms.
The SR-A3.0093.060-14.823 motor is equipped with a holding brake. Its holding torque is 10 Nm and the supply voltage rating is 24 Volts DC. The brake draws 1.06 Amps and its moment of inertia is 0.6 kg m2. The permissible ambient temperature for motor operation is 0 to 40 degrees Celsius. Ball bearings used on the motor have a minimum service life of 20,000 hours. The motor produces maximum 58 dB(A) noise when measured at 1 meter from the device. Insulation class of the motor unit is F in compliance with VDE 0530. The heat produced during operation is radiated via radiation and natural convection. Surface of the motor unit can reach temperatures of up to 100 degrees Celsius. Therefore, operators must use a touch guard to prevent injury.
