AC Brush Motor: 12 Slots, 24 Copper Bars, 48 Ends

In summary, rewinding an AC brush motor involves creating a clear diagram of the existing winding, including connections, wire gauge, and number of turns. It is important to duplicate the existing winding exactly for the rewound motor to function properly. The motor may have two smaller wires running in parallel to each of the 24 main wires, resulting in 48 ends instead of 24. Contacting the manufacturer or finding a wiring diagram for the specific motor model may provide more information on the wiring setup.

TL;DR Summary
Motor rewind
I have an AC brush motor it has 12 slots where copper wires go and 24 copper bars, if you take 12 wires and go in a slot and come out at different slot and as you go around you filled all the slots now you have 24 ends 2 wires out of each slot which you connect to the 24 copper bars. Heres the problem there are 2 wires connected to each copper bar, this means there are 48 ends so you need 24 wires or 4 wires sticking out of each slot, does this motor have 2 smaller wires runing in parreal?

You need to figure this out for your specific motor. The first step in rewinding a motor is to make a clear diagram of the existing winding. That includes the connections from commutator bar to slots to commutator bar, wire gauge, number of turns, how the end turns are laid in place, and more. This diagram is useful as a template of one way to make a rotor winding diagram, but it does not contain all of the necessary information:

Search terms rewind DC brush motor found several good hits.

I once spent a summer working in an electric motor rebuild shop. Take as long as necessary to fully understand the existing winding because you need to exactly duplicate it if you want the rewound motor to actually work.

It's possible that the motor has two smaller wires running in parallel to each of the 24 main wires. This would explain why there are 48 ends instead of just 24. However, without seeing the actual motor, it's difficult to say for sure. Have you tried contacting the manufacturer or looking for a wiring diagram for the specific motor model? That may provide more information on the wiring setup.
 

1. What is an AC brush motor?

An AC brush motor is an electric motor that uses alternating current (AC) to power its operation. It consists of a stator (stationary part) and a rotor (rotating part) and uses brushes and a commutator to transfer electrical energy to the rotor.

2. What are the specifications of the AC brush motor with 12 slots, 24 copper bars, and 48 ends?

The AC brush motor with 12 slots, 24 copper bars, and 48 ends refers to the number of slots in the stator, the number of copper bars in the rotor, and the number of ends in the winding. These specifications determine the motor's speed, torque, and power output.

3. How does an AC brush motor work?

An AC brush motor works by using the principle of electromagnetic induction. When an alternating current is passed through the stator windings, it creates a rotating magnetic field that interacts with the permanent magnets on the rotor, causing it to spin.

4. What are the advantages of using an AC brush motor?

AC brush motors are known for their simplicity, reliability, and low cost. They also have a high power-to-weight ratio, making them suitable for a wide range of applications. Additionally, they can operate at varying speeds and are easy to control.

5. What are the common applications of AC brush motors?

AC brush motors are commonly used in household appliances, power tools, and industrial machinery. They are also found in electric vehicles, elevators, and other transportation systems. Their versatility and cost-effectiveness make them a popular choice for various applications.
