Electronically commutated motor |
摘要 |
An electronically commutated motor has a rotor and a stator interacting with one another. A semiconductor control member controls a motor current supplied to the stator. An arrangement is provided that detects values of the motor current which surpass a preset threshold value and generates a first signal upon surpassing the threshold value. An arrangement is provided that determines rotational speed values of the motor, which surpass a preset rotational speed, and generates a second signal upon surpassing the preset rotational speed. An arrangement is provided that combines the first and second signals for generating a combined signal, wherein the combined signal acts substantially without temporal delay on the semiconductor control member and reduces the motor current to a value which is greater than zero.
