Abstract
An off-balance detection method comprises a plurality of off-balance detection schemes that utilize wash basket speed to detect an off-balance load condition at speed ranges that span the entire spin cycle and include speeds corresponding to natural frequencies of a mass comprising a wash tub and a wash basket. The schemes can be used alone or in combination with one or more of the other schemes. The off-balance detection method can further comprise a power limiting method to prevent motor overload when an off-balance condition is present.
