2AD132B-B35LB1-BS03-D2N1

Product Description

The 2AD132B-B35LB1-BS03-D2N1 is a 70 Nm AC servo motor part of the 2AD series of servos from Rexroth. This Asynchronous motor relies on the induction motor design where the rotor is rotated with the help of the stator which has 3 excitation coils that help generate electromagnetic fields causing the rotor to rotate. The 3 poles or coils in this motor can be excited with the same voltage of 168 volts AC but at a different frequency to control and regulate the speed of the motor.

This motor has a rotor inertia of 0.054 kgm^2 which is low and perfect as this would allow the motor to accelerate and decelerate its speed quickly without taking much time. The motor has a plain balanced shaft design which is perfect for torque transmission and also comes with a shaft sealing to prevent lubrication oil from spilling out and also to prevent dust and moisture from getting inside the motor from the front. The motor also features an Ingress Protection of IP 65 keeping it safe against dust and moisture prolonging the life of the motor.

The motor has a thermal time constant of 45 minutes allowing this motor to adjust its temperature quickly in under 45 minutes. The motor also has an axial blower fan to regulate the ambient air inside the motor to cool down the internals of the motor without needing an external fan or liquid cooling of any kind. A high-power motor should always be installed in a well-ventilated area to prevent overheating which may lead to a fire. Speaking of fire, the 2AD132B-B35LB1-BS03-D2N1 has an insulation class F protection rating against fire of up to 170 degrees Celsius.
