摘要

Consistent with other home appliances, washing machine manufacturers are continuously looking for methods to improve operational efficiency while simultaneously reducing cost. The washing machine spin operation is a critical component of this goal. Ideally, the drum is spun at a very high speed, typically 1.5K to 2K rpm, to extract the maximum amount of water in the least amount of time. Additionally, a lower-cost motor (with a minimal number of poles) and low-cost control circuitry (e.g., sensorless field-oriented control) are desired for meeting manufacturing cost targets. An advanced control technique called field weakening is available to help meet both of these goals without any additional cost. This article will explore the field weakening concept, how it is implemented, and the advantages it can bring to washing machine operation.
