Product Description

MAC112D-0-ED-4-C/130-B-0/WI522LV is a Bosch Rexroth servo motor. MAC series motors, in conjunction with TDM, KDS or DSC drive controllers, are rapid-response servo drives. These motors are well suited to applications such as machine tools, robotics, packaging machinery, and handling equipment. AC servo motors use permanent magnet motors and support electronic commutation. The permanent magnets are made with materials that enable low inertia motor construction. MAC motors provide high reliability and maintenance-free operation due to a brushless design and life-time lubricated motor bearings. These servo motors can be used within the working area of the machine. The motor housing is enclosed as per protection category IP65. In addition, the power, tacho feedback cables and encoder cables meet IP65 standards. Integrated thermos-switches on the motor and stator housing help prevents overload damage.

The MAC112D-0-ED-4-C/130-B-0/WI522LV motor has a convection cooled design that requires 0 to 45 degrees Celsius ambient temperature. Another requirement for rated output is 0 to 1000 meters elevation. If the temperature and elevation both exceed specified limits at the same time, the respective derating factors will multiply i.e. the rate of derating will increase. The motor supports tacho feedback and is equipped with an additional incremental encoder for position feedback. The main power connection is on side B of the IP65 rated motor housing. Performance specifications for the motor include 35 Nm continuous standstill torque, 63 Amps continuous standstill current, 0.023 kg m2 rotor moment of inertia, and 0.620 Nm/A torque constant. The resistance of the motor windings is 0.070 Ohms and their inductance is 1.3 millihenry. Thermal time constant of the servo motor is 120 minutes. Weight of the MAC112D-0-ED-4-C/130-B-0/WI522LV motor is 59 kilograms.
