Abstract
An ECM motor, including: a motor controller and a motor body. A microprocessor of the motor controller is connected to a first temperature detecting unit and a second temperature detecting unit disposed at different positions outside the ECM motor for detecting temperatures at the different positions. In operation, when the temperature difference between the first temperature Tand the second temperature Tis smaller than or equal to a preset value T, a first gear at the rotational speed Sis selected by the microprocessor and the motor is controlled to run constantly in the first gear at the rotational speed S. When the temperature difference between the first temperature Tand the second temperature Tis larger than the preset value T, a second rotational speed Sis selected by the microprocessor and the motor is controlled to run constantly in the second gear at the rotational speed S
