Product Description:
MAC112D-1-ED-1-B/130-A-0/J1250 is a Bosch Rexroth servo motor. It is part of the MAC motor product line. The motor is designed for surface cooling. This cooling method delivers higher rates of heat dissipation. As a result, surface cooled MAC motors deliver higher output torque and current and are suited to applications with higher load requirements. Under ideal operating conditions, the standstill torque of the MAC112D-1-ED-1-B/130-A-0/J1250 motor is 57 Nm and its standstill current output is 102 Amps. For comparison, the standstill torque and current of convection cooled MAC motors with the same specifications are 35 Nm and 63 Amps respectively. Nominal speed rating of the AC servo motor is 3000 RPM. Moment of inertia of the motor rotor is 0.023 kg m2. The torque constant at 20 degrees Celsius is 0.620 Nm/A.
Specifications for the winding include 0.070 Ohms resistance at 20 degrees Celsius and 1.3 millihenry inductance. Thermal time constant of the motor is 90 minutes. Thermal time constant is a measure of how quickly a system responds to a change in temperature. For comparison, the thermal time constant of convection cooled MAC motors with similar specifications is 120 minutes. Weight of the servo motor is 59 kilograms. Its length is 612 millimeters. Centering diameter of the motor is 130 millimeters. The motor flange size is 193 millimeters and the mounting hole diameter is 14 millimeters. Separate IP65 rated connections on the motor housing provide connectivity for power and feedback cables. The cable connectors are not supplied with the motor and must be ordered separately. Operators should consult product documentation to ensure they purchase the right connector. The IP65 rated motor housing provides robust ingress protection.
