An Electric Motor, also known as a Motor, is a device that converts electrical energy into mechanical energy in the form of rotational or linear motion. Most motors operate based on the principle of electromagnetic induction, where an electric current passing through coils in a magnetic field generates electromagnetic force, creating torque on the motor shaft.

1. Toshiba motor

The Toshiba motor (also known as Toshiba electric motor) is a three-phase asynchronous motor manufactured by Toshiba Corporation, Japan. Since its establishment in 1895, Toshiba has rapidly established itself as a global leader in the electric motor industry.

Nowaday, Toshiba motors are available in numerous countries such as Japan, the USA, Australia, China, and Vietnam. Especially, Toshiba Industrial Products Asia (TIPA), located in Amata Industrial Park, Dong Nai, specializes in manufacturing IE3 motors for the global market.

2. Motor classification

Based on power supply type

Direct Current Motor (DC Motor): Operates with a DC power supply.

Alternating Current Motor (AC Motor): Operates with an AC power supply.

Based on structure

Asynchronous motor (Induction Motor): Commonly used in industrial applications, manufacturing, and household equipment.

Synchronous Motor: Used in generators and automation systems.

Based on number of phases

Single-phase Motor: Suitable for small equipment such as fans, washing machines, and water pumps.

Three-phase Motor: Used in industrial applications and manufacturing plants due to its high power and efficiency.

3. Toshiba motor classification

Based on voltage

Single-phase Toshiba motor: 220V or 110V.

Three-phase Toshiba motor: 380V, 400V, or 415V.

Based on speed (RPM)

2-pole (2P): 2800 - 2900 RPM.

4-pole (4P): 1400 - 1500 RPM.

6-pole (6P): 900 - 1000 RPM.

8-pole (8P): 700 RPM.

Based on application and environment

IP44 - IP55 standard: Suitable for dry environments.

Water-resistant IP56: Suitable for wet or humid environments.

High-power motors (100HP - 400HP): Used in heavy-duty industries.

4. Structure of Toshiba motor

Stator (Stationary Part)

Motor Housing: Made from cast iron, aluminum, or steel to protect internal components.

Stator Core: Constructed using laminated electrical steel sheets.

Stator Windings: Made of pure copper to ensure effective power transmission and durability.

Rotor (Rotating Part)

Squirre-cage rotor: The most common type, ensuring stable motor operation with minimal maintenance.

Wound Rotor: Suitable for applications requiring high torque.

Motor Shaft: Made of high-strength alloy steel, connecting the rotor to the transmission system.

Auxiliary components

Cooling Fan: Mounted on the rotor shaft for heat dissipation.

Bearings: Reduce friction and extend motor lifespan.

Terminal Box: Contains electrical connectors for easy power supply connection.

5. Operating principle of Toshiba motor

The Toshiba motor operates based on the electromagnetic induction principle:

When an AC power supply is applied to the stator, a rotating magnetic field is generated.

This magnetic field induces electromotive force (EMF) and current in the rotor.

The electromagnetic force acts on the rotor, causing it to rotate in the direction of the magnetic field.

The motor continues to rotate until it reaches stable speed.

9. Notes when purchasing a motor

Identify the right motor type

(Single-phase/three-phase, synchronous/asynchronous, rotating speed, and suitable starting and control method for the application.)

Select suitable power and efficiency

(Avoid choosing too low a power rating, which may cause overload, or excessively high power, which may waste energy.)

Ensure compatible voltage, frequency, and phase

(Select a motor with voltage, frequency, and phase specifications compatible with the power supply at the installation site.)

Check dimensions, weight, and specifications

(Consider motor dimensions, weight, shaft length, shaft diameter, and terminal box position for easy installation.)

Select suitable IP protection rating

(Choose the appropriate IP rating for dust and water resistance to extend motor lifespan.)

Low noise and vibration

(Prioritize motors with low noise and vibration to ensure safe and comfortable operation.)

Brand and warranty

(Choose reputable brands with clear warranty policies and good technical support service to ensure quality and reduce maintenance costs.)
