Okay, let's break down how to decipher the winding scheme of a 12-coil motor. Knowing how the coils are connected is crucial to rewinding it correctly. Please provide the information you gathered from the coil wiring. The more detail you give, the better I can help you understand the winding type and how to rewind it.Specifically, I need information that answers these key questions:1. Coil Connections

How are the coils connected to each other? Do they form a series string? Are they in parallel? Can you describe the sequence? For example: "Coil 1 -> Coil 2 -> Coil 3 -> ... -> Coil 12" or "Coils 1-3 are in series, Coils 4-6 are in series, Coils 7-9 are in series, and Coils 10-12 are in series"2.

Phase Connections

How are the coil sets connected to the input power (phases)? For example: "Coils 1-4 are phase 1, Coils 5-8 are phase 2, Coils 9-12 are phase 3" OR "Coil 1 goes to terminal 1, Coil 4 goes to terminal 2, Coil 7 goes to terminal 3. Coil 12, coil 3 and coil 6 are connected together".
3.

Number of Poles

Did you see any obvious pairing of coils to suggest the number of magnetic poles the motor was designed to have? For example, are coils 1&7 close and opposite, then the next pole would be coils 2 & 8?4.

Physical Arrangement

How are the coils physically arranged around the stator? Are they evenly spaced? Are there any noticeable groupings or asymmetries?5.

Number of Leads

How many wires came out of the motor? This tells us how many phases it has (usually 3 or 6 for a three-phase motor).6.

Winding Direction

If possible, note the winding direction of each coil (clockwise or counter-clockwise as you look at it from one end of the stator). This is really important!7.

Voltage & Current

If there is ANY marking on the motor, please specify it! even a single number might help.

Why this information is important



Series vs. Parallel

This determines the voltage and current relationship. Series connections increase voltage, while parallel connections increase current.

Phase Configuration

Identifies if the motor is single-phase, three-phase (star or delta connected), or another configuration.

Number of Poles

Dictates the speed of the motor. A 2-pole motor will run faster than a 4-pole motor with the same frequency.

Winding Direction

If you wind a coil backwards it will work against the motor!

How to Gather the Information


Sketch a Diagram

Draw a simple diagram of the stator and number the coils 1 through 12.2.

Trace the Wires

Carefully trace the connections between the coils. Use a multimeter in continuity mode to confirm connections. Note them on your diagram.3.

Note Wire Colors

If the original wiring has different colors, note which color is connected to each coil. This can help with consistency during rewinding.4.

Take Pictures

Take clear pictures of the coil arrangement, the connections, and any markings on the motor.Once you provide this information, I can help you:

Identify the Winding Type

(e.g., lap winding, wave winding, concentric winding)

Determine the Number of Poles Suggest a suitable rewinding procedure Calculate the required wire gauge and number of turns
