Motors

The history of motors is something that that goes back to times when the fundamentals of electromagnetic induction were first introduced. Since then the core function of these motors remains the same, which is to convert electrical current into mechanical force.

Since the introduction of the motor there have been many different versions developed such as the following types of motors:

• AC motors - the most popular and simple form of an AC motor is the three-phase AC induction motor, which is also known as the squirrel cage motor.
• Stepper motors – these are electro-mechanical devices that convert current into torque output
• DC motors – these motors convert mechanical force into electrical energy through the use of a generator or dynamo. This form of motor can be divided into two types, which are brushed DC motors and brushless DC motors
• Linear motors – this form of motor produces linear force along it’s length instead of the conventional torque that is seen in other motors

All of these represent forms of electric motors, which are practically used everywhere around us. Nearly everything we use throughout our home requires the use of an electric motor. For example your microwave, fridge freezer, vacuum cleaner, hair dryer and car heaters and radiators all require the use of an electric motor. So just exactly how do these motors work?

Motors use electromagnetic fields that are used to generate motion. They function on the principle of magnetism. Most, but not all, work on the concept that there is a fixed magnet on the outside, which is called the field magnet and inside lies an armature that carries the current. As soon as the current passes through the wired armature it turns into an electromagnet with opposite polarity to the field magnet.

Due to there wide use motors play a key role to many businesses and the construction industry. So if you find yourself in need of a specific motor then you have come to the right place.

Here at Howcroft Industrial Supplies we are leading experts in all materials and tools associated with the construction industry. We can pretty much supply you with any form of motor that you need, even if we don’t currently keep it in stock. This is thanks to the fact that we are able to order in a vast array of motors to cover all of your needs.
