Tips: Basic Structure of Induction motor

The main structure of induction motor is composed of two parts stator and rotor where there is an air gap between them. In addition, there are end bells, bearings, motor frame and other components.

stator
Stator is a fixed part of asynchronous motor, consisting of motor frame, iron core and windings. Motor frame is the shell of motor, playing the role of supporting the motor, which is made of iron. Stator iron core is a hollow cylinder, stacked up with 0.5 mm thick silicon steel sheets. Stator windings are wound with insulated copper wires and embedded in the stator slot, which are separated by insulating material between the windings and the slot.
Air gap
The air gap of asynchronous motor is much smaller than the direct current motor with the same capacity, 0.2 ~ 1.0mm on average for medium and small asynchronous motor.
Rotor
Motor rotor is composed of iron core, windings and revolving shaft. Rotor core is also a part of the magnetic circuit, generally stacked by silicon steels and fixed on the revolving shaft. Wound-type rotor winding can be connected into star or delta. In general, the small capacity rotor is connected into triangle; the large and medium capacity one is connected into star. The winding structure of squirrel-cage rotor is quite different from the one of stator. There are slots on the rotor iron core with a bar on each slot. Two ends of iron core that connect all the bars to the external of slots respectively form a short circuit. If the iron core is removed from the stator, the windings shape is like a squirrel cage. Some bars are made of copper, and some are aluminum.

3 Phase Induction Motor Wiring

In this video, ATO takes a 1hp (0.75kW) 220V/380V induction motor as example to explain the motor wiring. ATO first changes the wiring of induction motor from star connection to delta connection. When the induction motor is connected in delta connection, the rated voltage of motor is 220V, and when connected in star connection, the rated voltage is 380V. To demonstrate this change clearly, the induction motor is also connected to ATO 1-phase in 3-phase out VFD and it runs normally under the control of VFD.

Three-phase Motor to Single-phase (380V to 220V)

If a frequency converter is beyond your budget or availability, one way to run a three-phase motor from single-phase power is to use capacitors. In this tutorial, the step-by-step process of adapting a motor for single-phase operation is demonstrated by showing the correct capacitor sizing and wiring configuration.

Two-wire Control Wiring of VFD Forward Motor with Push Button

In this video we've guided you through how to do VFD control wiring with a self-lock push button switch to run the motor in forward direction. We've covered everything from wiring to programming and even a test run. So just watch it through and hope you'll find it informative and helpful.

Three-phase Motor Forward and Reverse Wiring and PLC Programming

To achieve forward and reverse rotation of a three-phase asynchronous motor, you only need to swap the positions of any two phase wires. (Single-phase asynchronous motors need to be wired according to the instructions to achieve forward and reverse rotation).

3-phase motor reverse connection

In this video, we have 120V/220V/240/380V/415V AC motors with power from 1hp~100hp, widely used to drive various industrial machines such as fans, pumps, machine tools.
