Product Description

MAC115A-0-FS-3-C/130-A-0/S001 is a high-performance AC servo motor. It is part of the MAC series from Bosch Rexroth. The motor has a shaft with keyway. The keyway prevents slippage and provides a reliable method for transmitting torque between the shaft and the attached machine. Diameter of the motor shaft is 32 millimeters. Approximately 58 millimeters of the shaft are outside the main housing. Bosch has designed the MAC115A-0-FS-3-C/130-A-0/S001 motor for natural convection cooling. Its nominal speed is 3000 RPM. The continuous output torque at standstill is 28 Nm and the continuous output current at standstill is 48.8 Amps. For applications with higher load requirements, operators can order MAC motors with surface cooling. Moment of inertia of the rotor is 0.0123 kg m2. This low inertia is enabled by the use of high-quality permanent magnets.

The torque constant of the MAC115A-0-FS-3-C/130-A-0/S001 motor is 0.588 Nm/A at 20 degrees Celsius. Resistance of the motor windings is 0.076 Ohms at 20 degrees Celsius. Inductance of the motor windings is 1.6 millihenry. Integrated temperature sensors on the windings prevent damage from overloads. Thermal time constant of the AC servo motor is 90 minutes. Weight of the motor is 33 kilograms. Length of the motor is 357 millimeters and its centering diameter is 130 millimeters. The motor housing has a flange at one end for mounting. This flange has four mounting holes for mounting screws. Diameter of the each of the holes on the motor flange is 14 millimeters. MAC motors must be operated within ambient limits recommended by Bosch Rexroth. Relevant precautions related to MAC motor operation are listed in the product manual. Failure to follow safety precautions can lead to injury and equipment damage.
