General Purpose Motors

Get The Best General Purpose Motors (Induction Motors) At the Best Prices 

General-purpose motors, a.k.a. (Induction motors), are one of the most essential devices for every household and small-scale to large-scale industries. They can be found everywhere, from washing machines to fans, and refrigerators to industrial compressors and conveyor belts. Their work module is based on electromechanical energy, which is formed by transforming electrical energy into mechanical energy to operate different types of devices. They are workhorses in nearly every industry. Induction motors are a much newer concept that became necessary when motors were driven by the VFDs (general-purpose AC motors). 

General-purpose motors can be used with frequency converters in many applications and are available in different types, and the most demanding ones are 3-phase induction motors and single-phase induction motors. These general-purpose AC motors use a rotating magnetic field that does not require brushes and therefore requires less maintenance. If you are also looking for the best general-purpose induction motors, then you are at the right place. At Moglix, you can find a wide range of general-purpose motors (AC motors) from reputed brands like Havells, Crompton, Siemens, ABB, Hindustan, SONEE-DX, etc., to fulfil your every basic to advanced requirement.

Different types of General Purpose Motors available in the market 

Before you finalise the purchase, you must be aware of every type of general-purpose motor to know its principles and applications that suit your work procedure and purpose.  

Permanent Magnet Motors - This general-purpose electric motor uses a permanent magnet to create field flux. This type of DC motor provides great starting torque and has good speed regulation, but torque is limited, so they are typically found in low horsepower applications.

Series DC Motors - In a series DC motor, the field is wound with a few turns of a large wire carrying the full armature current. Typically, series DC motors create a large amount of starting torque but cannot regulate speed and can even be damaged by running with no load. These limitations are not a good option for variable-speed drive applications.

Shunt DC Motors - In shunt DC motors, the field is connected in parallel (shunt) with the armature windings. These motors offer great speed regulation since the shunt field can be excited separately from the armature windings, offering simplified reversing controls.

Compound DC Motors - Compound DC motors, like shunt DC motors, have a separate shunt field. Compound DC motors have good starting torque but may experience control problems in variable-speed drive applications.

Phase-Type General Purpose Motor

Single-phase motor: As the name suggests, the motor is operated in single-phase alternating current (AC) and is widely used in homes and small-scale industries to process different work. It requires a starting mechanism and is designed in different ways, like capacitor start, split phase and shaded-pole motors.

Single-phase open-enclosed motor: In this type of induction motor, the enclosure is opened to allow air flow. 1- Phase motors are better in cooling mechanisms, minimising overheating and continuous operation. These AC induction motors can be used in pumps, fans, blowers, etc.

Three-phase induction motors: These are also a type of general-purpose motor that uses a 3-phase power supply to operate. They are more efficient than single-phase motors and well-suited for heavy applications.  Additionally, a shelf start mechanism makes them a suitable device for large industries.

GNEM open motors: A general-purpose motor which is designed to majorly use in a clean environment with an ability to operate on 50Hz to 60 Hz frequencies. They can easily handle and operate on multiple voltages, which leads to better energy efficiency.  

What Are the Specifications of a General-purpose Motor (Induction Motor)  

Knowing every key specification of an induction AC motor helps users find a suitable device for them. You need to have precise information to meet all the requirements you are looking for.

>>Power Output: To verify the work efficiency and ability to drive various tasks depends on the power output of an induction motor. You can find the range from 0.25HP to 100HP induction motor.

• Small General-Purpose Induction Motor: A 1HP to 3HP single-phase motor is sufficient for applications like fans, pumps and other small appliances
• Medium General-Purpose Induction Motor: An Around 10HP induction motor is enough to drive big machines and conveyors.
• Large General-Purpose Induction Motor: 100HP is required to drive machines like heavy pumps and industrial compressors.

>>Voltage Output: It is also crucial to know about the overall voltage oypt an induction motor, which impacts the overall efficiency of speed, torque and performance. A 230V with single phase and 415V three-phase is typically used in India, for better efficiency without any damage.

>>Speed RPM: The speed and RPM of an induction AC motor depend on the number of poles it contains. However, frequency is also important for a motor to determine the speed. Mostly used are (75, 1000, 1500, 3000 RPM).

>>Efficiency: Before you finalise the purchase, it is necessary to understand the overall efficiency of the general-purpose AC motor, which should in between 75% to 95%. It reduces the cost by saving your energy and becomes more cost-effective, and lower operation costs.

Points to consider while buying the Best General Purpose AC Motors

Motor phase -  Domestic electricity connection has a single-phase power supply or three-phase power supply, and we should choose a single-phase model or three-phase model accordingly. Single-phase general-purpose motors can be operated on a three-phase network. However, the reverse is not current. 

Motor Current - It is a fundamental requirement for the operation of any motor, and incorrect current ratings can cause the product to overheat and degrade performance. Operating current is the amount of current a motor draws under normal load. Choosing a general-purpose AC motor that draws too much current under normal load can lead to overheating and eventual damage. Motor current is measured in amperes. 

Motor voltage -  Voltage is responsible for maintaining constant current flow to the motor and avoiding reverse current flow. Voltage is directly proportional to torque. Selecting a motor with a value higher than the load can result in excessive current and overheating, affecting performance. 

RPM - RPM is a key factor in choosing a motor, and it depends entirely on the basic applications such as juicers, flour mills, and small lifting applications. We recommend choosing a  1440 rpm motor. For more industrial applications such as pressure fans and industrial washing machines, 2880 rpm can be selected.

Motor size -  It plays an important role in assembling the engine into the desired configuration. Depending on the existing installation type and junction box position, frame sizes are standardised and should be selected accordingly.
