Construction and Structure of General-Purpose Motors

The primary purpose of a general-purpose motor is to serve the people in a typical environment. However, for harsh conditions, specifically designed motors are used. This motor contains the following components which are directly involved in the motor functionality:

The Rotor:

The other name for this component is the armature which rotates in the motor. When it turns, it shifts its torque towards the shaft, which helps load and unload through its mechanical force. It contains permanent magnets for the generation of alternating current.

The Stator:

The critical component of the motor is its stator. It can be a permanent or temporary magnet. If the no. of coils increases, it produces a more magnetic field. This magnetic field helps the rotor to move through its interaction with the windings.

Instead of a single large stator sheet, multiple small sheets (laminations) are used, reducing energy losses.

The Bearings:

The moving rotor needs support which is provided by the bearings. It also keeps a small air gap between the stator and rotor, which helps in its efficient working. The extended outer part of the motor from the bearing is termed the shaft.

The Windings:

The multiple conductive wires make the windings. These tiny wires are enfolded around the stator (containing magnetic material). This part helps pass the current, which generates a magnetic field further leading to the rotation of the rotor.

The Air Gap:

The motor’s overall efficiency and strength are under this factor’s control. This small gap is present between the stator and rotor. If this distance is increased, the windings will need more current to produce more magnetic fields. In this way, the productivity of the motor is lowered.

The Commutator:

The main object of the commutator is to oppose the direction of the current which is coming from the external circuit. When it reverses the present, the order of the torque is also changed. It happens to convert the alternating current into a direct current.

It contains copper fragments that are joined with the immovable (stator) and the movable part (rotor) of the motor.

These six components are found in general-purpose motors. Due to safety reasons, these components are enclosed in a protective covering. This covering can be opened or closed.

Features of General-Purpose Motor

The general-purpose motor that this brand offers is full of extraordinary features. Some of its characteristics are mentioned below:

  • Some sensors are attached to the motor to control its functioning at high temperatures.
  • The switches are coated with beryllium which resists corrosion.
  • The bearings are composed of rubber bands.
  • The surface paint is done with corrosion-free material.
  • All the internal components are corrosion-free.
  • It can bear a temperature of 40o
  • IP54 protection is ensured by a three-phase general-purpose motor which makes it weatherproof.
  • All the gaskets are also covered and have the molded capacitor.
  • The stator is usually V-shaped.
  • A device named a grease collector is also connected with large-sized motors.
  • Its power ranges in horsepower from 13 to 700.
  • Based on voltage, the motor can be a 220V AC motor, 380V motor, 400V motor, and 660V motor.
  • The sturdy nature of the material is due to cast iron, rolled steel, and Al.
  • Its lifespan is much higher compared to other motors. Due to this, you can utilize its energy for several years without any hindrance.
  • of poles is variable for each motor according to its category. It can be 2 pole motor, 4-pole motor, 6-pole motor, 8-pole motor, and 10-pole motor.
