Many are unsure about why electric motor rewinding is a necessary service. Motor rewinding is a process that can help in the repair of shorted, grounded or damaged coils in a motor. A motor rewind means that a coil is rewound and reinstalled for the necessary armatures or other components.
What is rewinding of electric motor?
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. The rewinding process is not necessarily as simple as it may sound, however.
Why do we rewind motor?
Rewinding an electric motor can improve insulation resistance and can improve the efficiency of your motor at the same time. … While most malfunctioning motors can benefit from the rewinding process, some motors can be so deeply damaged or beyond their performance lifespan that the only realistic option is a replacement.
What is the type of rewinding process?
Given the sheer number of different motors and winding patterns, the rewinding process can vary greatly. However, it generally involves cutting the original windings out of the motor’s stator or armature and replacing them with new coils made from wire of the same basic type and gauge.
What are the types of motor winding?
The motor winding types are two types which include the following.
- Stator Winding.
- Rotor winding.
What’s the meaning of rewinding?
transitive verb. : to wind again especially : to reverse the winding of rewind film. rewind. noun. re·wind | ˈrē-ˌwīnd , (ˌ)rē-ˈwīnd
Is it worth rewinding a motor?
Having your motor rewound is only about 40% of the cost of purchasing a brand new motor. In addition to saving money, choosing to rewind your motor can also help the environment. The rewind process has a very minimal environmental impact when compared to the carbon costs of creating a brand new motor.
What are the materials used for motor rewinding?
Copper is the most common magnet wire choice due to its high conductivity and relatively low cost. For most motors like the one shown below, we use copper with a very thin enamel coating and tightly wrap the wire to create the winding that will build the electromagnetic field to drive the motor.
How are winding turns calculated?
Call the number of turns N and the length l. Calculate the inductance associated with the winding using the formula L = (u0 * A * N^2)/l where u0 is the permeability of free space at 12.56 x 10^-7. If N is 100 turns, l is 6 meters and A is 7.069 square meters.
How do you rewind a 3 phase motor?
3 Steps to 3 Phase Motor Rewinding
- 1 – Determine the Winding Data. Before motor rewinding can begin, we must determine the winding data. …
- 2 – Prep the Stator for New Coil Insertion. The stator slots will be investigated for any sharp edges and filed when necessary prior to coil insertion. …
- 3 – Insert Coils.
What is a 3 phase motor?
Three-phase motors are a type of AC motor that is a specific example of a polyphase motor. These motors can be either an induction motor (also called an asynchronous motor) or a synchronous motor. The motors consist of three main components – the stator, the rotor, and the enclosure.
How are electric motors wound?
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.

What do I do with an old water pump?
You could just sell it all for scrap. Just Google a scrap metal yard close to you. Even if you don’t get much cash for it at least it gets recycled instead of taking up room in a landfill.
