Discussion Overview

The discussion revolves around the feasibility of wiring a Whirlpool washing machine motor (model 8529935) as an AC generator. Participants explore various aspects of this conversion, including wiring configurations, the use of permanent magnets, and practical considerations for DIY applications.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • Some participants identify the motor as a "Gentle Annie" motor and describe its wiring, noting that it has four main wires: red and brown for the stator, and yellow and gray for the brush wires.
  • One participant suggests specific wiring configurations for clockwise and anticlockwise rotation, detailing how to connect the stator and brush wires.
  • Another participant raises the idea that generating power from the motor may require a DC feed to one of the windings to provide a field, questioning the convenience of this approach.
  • There is mention of the possibility of using permanent magnets in the motor to generate power or initiate self-excitation.
  • A participant discusses the practical implications of using the motor in a DIY project, suggesting that the size of the power source, such as a wind turbine, is relevant to the motor's effectiveness as a generator.
  • Concerns are raised about the challenges of mounting and driving a larger motor, while also noting that a smaller permanent magnet motor might be more suitable for simple projects.
  • One participant proposes using an electric drill to turn the motor as a potential method for generating power.

Areas of Agreement / Disagreement

Participants express a range of views on the feasibility and practicality of using the washing machine motor as a generator. There is no consensus on the best approach, and multiple competing ideas are presented regarding wiring, the use of permanent magnets, and project viability.

Contextual Notes

Participants discuss various assumptions about the motor's capabilities and the conditions under which it could function as a generator. Limitations regarding the power output and the suitability of the motor for different DIY applications are noted but remain unresolved.

what color wires would be the brush wires in this motor:8529935

Welcome to PF.

I think the motor you are referring to is: Whirlpool OEM Part #WP8529935
I believe they are colloquially known as a "Gentle Annie" motor.
Is this the motor?

Does this make sense?
Whirlpool OEM Part #WP8529935 has four main wires:
red and brown (stator wires) and yellow and gray (brush wires).

For clockwise rotation: Join the brown (stator) wire to the yellow (brush) wire.
Pass the line and neutral power through the red and gray wires.

For anticlockwise rotation: Join the brown (stator) wire to the gray (brush) wire. Pass the line and neutral power through the red and yellow wires.

He wants a Generator so he will need a feed of DC(?) to one of the windings to provide a Field. Possible, under some circs but maybe not convenient. Personally, I'd be inclined to 'not start from here' unless it was part of a bet.
Low power motors with a permanent magnet are the usual source of generator projects.
 
I have seen how some people place permanent magnets in those motors. That may be sufficient to generate, or it may be to initiate self excitement.

This is a DIY project which means a hypothetical or practical application before the OP's motor can be considered suitable - possible power out when driven by a particular source. If the source is a wind turbine then the possible size would be highly relevant because a small turbine may not even turn the generator.

If it's just a matter of proving a point by building a model wind power generator then a small (very low cost) permanent magnet motor could be turned by a small (say <1m diameter) turbine and light some LEDs. A very straightforward project with high hopes of success. A big motor could be problematical to mount and drive.

OTOH, if the OP has open land and workshop facilities, the washing machine motor project would be possible. The field winding could be fed by some dc or even start by its magnetic remnance. Turning it with an electric drill could be a way forward.
