While some sources might suggest there is no formula as such for every single aspect of stator core design, specific electrical and winding parameters rely on established equations.how to make formula Motor rewinding ???

Turns per Coil and Coil Pitch Calculation

A crucial step is determining the number of turns per coil. This can be derived from voltage and flux calculations.The emf induced per parallel path (E) can be calculated using the formula:E = (Φ * N * Z * P) / 60, where: Φ = Flux per pole ...

The fundamental formula for induced EMF in a generator is:

E = (Φ * N * Z * P) / 60

Where:

* E is the induced EMF (Voltage)

* Φ is the flux per pole

* N is the speed of the conductor in RPM

* Z is the total number of conductors

* P is the number of poles

From this, the total number of conductors (Z) can be calculated.Example of pitch factorcalculation: A four pole48 slotmotor has a pole pitch of 12slots. (48/4). A full pitched lap coil would therefore span 12slots. Subsequently, the total number of conductors is divided by the number of coils per phase to find the turns per coil.

The coil pitch is the span of a coil in terms of slots. A full-pitched coil would span a full pole pitch. For a 48 slot motor with 4 poles, a full-pitched coil would span 12 slots (48 / 4)What is the formula for calculating a stator core and .... However, short-pitched windings are often employed to improve waveform and reduce harmonics. The pitch factor is a crucial multiplier in EMF calculations that accounts for this short pitching.

This method is common for efficient utilization of slots.

Practical Considerations in Rewinding

Beyond the theoretical formula and calculation, practical aspects are vital for a successful rewinding project:

1. Material Quality: Using high-quality insulating materials (like Mylar or Nomex) for slot liners and phase barriers is critical to prevent short circuits and ensure the longevity of the winding.

2. Tight Tolerances: Proper insertion of coils into the 48 slots is crucial. Coils should fit snugly to prevent movement and mechanical damage. You can use wooden stick to put winding in slots.

3.As part of the study, a new flux barrier was introduced and experimented on the rotor pole of a50 kW, 4-pole salient-pole synchronousgeneratorwithout damper ... Inter-coil Insulation: Ensuring adequate insulation between coils of different phases and between coils and the stator iron is essential.
