Product Description
For industries with tough application requirements, Rexroth MAC112B-0-GD-4-C/130-B-0/WI524LV/S021 AC Servo Motor is a robust and quiet motor. With surface cooling, the motor delivers a continuous torque of 29 Nm at stationary rated speed of 3000 min__. It tolerates a maximum peak pulse current of 223 Amperes and a constant current of 41.0 Amperes (or distributed with surface cooling 75.0 Amperes).
U-shaped cogging attached to rotor with a mass at the moment of inertia of 120 x 10__ kgm^2 contribute to appreciable adroit controls accompanied with gradual acceleration. The motor is still usable and functional as the performances are made every satisfaction, where winding resistance is 0.090 Ohm, inductance is 1.2 mH and torque constant of 0.430 Nm/A is realizable at 20 degrees Celsius. This is achieved with no overheating or rather under muande cycles, thermal time constant of 90 (60 in cases of surface cooling) could be experienced. Weighing 36 Kg, the comb motor cannot go through stress as it is constructed for heavy-duty usage.
One of torque limitation features, which services along with a motor and is meant to be rotor holding, can be incorporated to the motor. When there is no current, the closing mechanism works because of the closed circuit principle. The axis does not spin because there is a magnetic force which locks the brake. This reduces the magnetism at 24V DCA so as to allow removal of the brake. It is the customer responsibility about the control of the holding brake and regulation over here may be performed with the help of hardware switch or PLC. The Applications Manual with Servo Drive Modules TDM and KDS for MAC Servo Drives provides basic information how to perform the adjusting of braking.
