Two Speed motors - Free download as Word Doc (.doc / .docx), PDF File (.pdf), Text File (.txt) or read online for free. Two speed electric motors can have either two separate windings or a Dahlander winding. Two separate windings allow for different pole numbers and speed ratios, while Dahlander winding is limited to ratios like 2:4, 4:8, or 6:12. Connection types for the windings include Delta/Delta, Wye/Wye, and Delta/Wye. An engine room blower motor was rewound, having a two separate winding consisting of a 6-pole and 12-pole configuration in 72 slots. The rewinding process involved removing the existing windings, cleaning the slots, reinserting new windings in the proper patterns, and testing before reassembly.
