I wasn't going too far down the 'how to choose a replacement motor' route since it's reasonably well documented in numerous places and it wasn't the question which was asked, but feel free. What you see here is a fully automatic winding process. The working principle of the electric motor mainly depends on the interaction of magnetic and electric field.The electric motor is mainly classified into two types. We provide our valued customers with sales, service and support from our two strategic locations situated in Cranbrook and Castlegar BC. It’s a pleasure to watch fabrication process of windings in the factories. This non-invasive test of winding resistance helps to pinpoint problems regarding windings in the stator or rotor part of an electrical machine. Definition: Electric motor is the electro-mechanical machine which converts the electrical energy into mechanical energy.In other words, the devices which produce rotational force is known as the motor. The rewinding process is not necessarily as simple as it may sound, however. has been operating in the Kootenays as its locally based electric motor repair experts for 25 years.

Even allowing for old horses being stronger than modern ones the replacement motor is 5.5kW, chosen partly on the basis of low speed torque and partly on the basis of mechanical compatibility. Electric motor rewinding involves three basic steps: removal or stripping of the winding (coils), Inserting and connecting new winding (coils), and insulating the complete winding. You do need to consider the effect of potentially over-powering the machine at the higher speeds.Īs an example I had one of these 3-speed motors on my old lathe which was nominally rated at 3HP. Electrical Adhesive Tapes, Lacing Tapes, Motor Terminal Blocks, Motor Cooling Fans, Slot Closures and Wedges, Thermal Protectors, PTC, Motor Capacitors. By oversizing the motor you have sufficient torque at the lower speeds, while maintaining the top speed. Absolutely - the saving grace being that these old multi-speed motors are quite chunky, so you can usually get a much more powerful standard motor into the space vacated.
