Is motor rewinding a good business?
Is motor rewinding a good business?
In view of ever growing use of several new domestic appliances there is need rewinding and repair have good market potential in Govt. sector as well as in semi urban and rural sector. There is new trend of use of automatic/ CNC winding / rewinding process.
What is the cost of motor rewinding?
The avg. market price of Electric Motor Rewinding in India is Rs 9,000/ Unit.
Is rewinding a motor hard?
An electric motor rewind is a delicate process, and removing the dirt, old insulation and grime accumulated after years of use within a motor is a difficult dirty practice (in most cases).
What is motor rewinding work?
What is Involved in Rewinding an 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.
How is motor winding 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.

Why do motors need rewinding?
Low insulation resistance is a problem that happens naturally over the course of a motor’s life and is triggered by contamination, vibration, and power surges. Rewinding an electric motor can improve insulation resistance and can improve the efficiency of your motor at the same time.
