Product Description
Indramat Rexroth manufactures AC servo motors and MAC112B-0-GD-4-C/180-A-1/WA605XX/S011 is one of the variants that offers a rated speed of 3000 rpm. It has a natural convection cooling method, whereas the continuous current at a standstill and continuous torque at a standstill of this machine are 41 A, and 16 Nm respectively. They have excellent performance and work on a wide speed spectrum. The maximum peak of pulse current is 223 A, and the mass of the machine excluding the encoder and holding brake is 36 kg. This variant is equipped with standard holding brakes that operate on a 14V DC power supply. The holding brake weighs 1.1 kg, and the moment of inertia of the holding brake is 3.6 x 10-4 kgm2. The total moment of inertia of the rotor is 123.6 x 10-4 kgm2. The MAC112B-0-GD-4-C/180-A-1/WA605XX/S011 comes with standard type tacho and is equipped with mounted incremental or absolute encoder.
The upper limit of the permissible storage and transport temperature is 80 degrees centigrade whereas the lower limits are -20 degree centigrade. To protect the motor housing, it is painted in primal black that has the code RAL-9005. The winding inductance of the motor is 1.2 mH, and the winding resistance of this variant is 0.09 ohms. Motor winding resistance and inductance are the fundamental properties of the wire coils that form the rotor and stator. There are seven categories of classes of insulation based on the maximum temperature limits. These are Y, A, E, B, F, H, and C, and this special motor MAC112B-0-GD-4-C/180-A-1/WA605XX/S011 has F category insulation. The torque constant of this variant is 0.43 Nm/A at 20 degrees centigrade. The thermal time constant of this AC servo motor is 90 minutes against the natural convection cooling method.
