Product Description
The MAC112A-0-ZD-4-C/130-B-1/WI561BX from Rexroth is an AC servo motor that is part of their MAC lineup. This AC servo motor has a diameter of 130 mm and weighs 25 kg. The MAC112A-0-ZD-4-C/130-B-1/WI561BX has a frame size of A while the size of the motor is 112. This motor has a pretty robust design as it's intended for usage in a highly toxic environment hence the IP 67 protection rating is very beneficial. It is also coated with a black prime paint to prevent oxidation on the chassis of the motor.
The MAC112A-0-ZD-4-C/130-B-1/WI561BX can reach a speed of up to 1500 rpm when operating under normal conditions, but it can also reach up to 4500 rpm when using high-speed bearings with proper lubrication oil. Speaking of lubrication oil, the MAC112A-0-ZD-4-C/130-B-1/WI561BX features a shaft seal that allows the motor to keep the front sealed to prevent lubricant leakage and also to avoid dust from getting inside. The shaft has a keyway design which is needed for torque transmission to keep the attached component secure and to prevent the shaft from bending or breaking while rotating.
This particular model features an incremental encoder for precisely moving the shaft toward the requested position with minimum error. The encoder requires 5 volts DC supply to operate and consumes approximately 30 mA of current. It also generates negative square wave pulses for shaft rotation in a counterclockwise direction to help differentiate the direction of rotation. This motor can be mounted using a flange mount as it is much more secure and stable, and it helps absorb much of the vibration without the need for a dampener.
