Overview

The REXROTH Rexroth motor R901531121 comes with a one-year warranty. The three-phase asynchronous motor mainly consists of a stator and a rotor. The stator is the stationary part of the motor, consisting of the stator core, stator winding, and frame. The stator core is a part of the motor's magnetic circuit, on which the stator winding is placed. When three-phase AC power is applied, it generates a rotating magnetic field. The rotor is the rotating part of the motor, consisting of the rotor iron core and rotor winding. The rotor winding induces current under the action of a rotating magnetic field, and interacts with the magnetic field to generate electromagnetic torque, driving the motor to rotate.

Principle:

When a symmetrical three-phase AC rotating magnetic field is introduced into the three-phase stator winding. Due to the rotating magnetic field rotating at a speed of n1, when the rotor conductor is initially static, a clockwise direction stop is generated along the inner circular space of the stator and rotor at a synchronous speed of n1. Therefore, the rotor conductor will cut the rotating magnetic field of the stator and generate induced electromotive force (induced electromotive force induces current. The current carrying conductor of the rotor is subjected to electromagnetic force in the stator magnetic field (the direction of the force is determined by the right-hand rule). Due to the short-circuit ring at both ends of the rotor conductor, under the action of induced electromotive force, a direction that is basically consistent with the direction of induced electromotive force will be generated in the rotor conductor (determined by the left-hand rule). Electromagnetic force generates electromagnetic torque on the rotor shaft, driving the rotor to rotate in the direction of the rotating magnetic field.

Working process:

Induction of rotor conductor (generating current)

The rotating magnetic field generated by the stator rotates at a synchronous speed ns at high speed.

The conductors (squirrel cage bars or winding wires) on the stationary rotor continuously cut through the magnetic field lines of this rotating magnetic field.

According to Faraday's law of electromagnetic induction, induced electromotive force is generated inside these rotor conductors.

Due to the fact that the conductor of the squirrel cage rotor is connected at both ends by a short-circuit ring (or the wire wound rotor itself is a closed loop), this induced electromotive force will form a closed induced current inside the rotor conductor.

The generation of electromagnetic torque (force generation)

Now, there is induced current flowing through the rotor conductors, while they are also in the rotating magnetic field of the stator.

According to Ampere's law of force (the action of force on an electrified conductor in a magnetic field), every current carrying rotor conductor will be subjected to electromagnetic force exerted by the magnetic field.

All the electromagnetic forces acting on the rotor conductors combine to form an electromagnetic torque.

Under the drive of this electromagnetic torque, the rotor begins to rotate.
