摘要： An improved method of commutating an electronically commutated DC motor shuts off application of power between the end of one current pulse and the beginning of the subsequent current pulse. Based upon the instantaneous rotation speed, one calculates at what instant to shut off the power. During the power interruption, the disconnected winding is operated in short-circuit mode using two MOSFET transistors, and the decay of the current is monitored. When the current reaches a predetermined reduced value, the terminals of the winding are switched to a high-resistance state, until the subsequent current pulse is started. This has the advantage that less reactive power occurs during operation, and one need not install as bulky a storage capacitor as the capacitors used heretofore.

摘要： A method of limiting current in a DC motor acts on a full bridge circuit (137) through which the stator winding arrangement (102) of that motor is supplied with current. Upon response of the current limiter, energy supply to the stator winding arrangement (102) from the DC power network is interrupted. The stator winding arrangement is then operated substantially in short circuit via semiconductor switches of the full bridge circuit, and the decaying current flowing in that context serves substantially to continue driving the motor. When that current has reached a lower value, energy supply from the DC power network to the motor is once again activated. The effective value of the current flowing to the motor is preferably reduced when the current limiter responds. The time period during which that current flows, in the form of current blocks, is then increased in compensatory fashion.

摘要： An improved method, for obtaining a datum concerning the rotation speed (n) of a rotating object, such as a motor rotor (32), offers high precision. Typically, the motor has a sensor (61) which supplies a sensor signal that has, for each revolution of the rotor, a plurality A of events such as pulses or pulse edges which are counted by a microprocessor (23) associated with the motor. In order to keep the computation load on the microprocessor from increasing as the rotor speed increases, yet maintain high precision, the measurement is done over a full rotation of the rotor, starts at a first signal event (176), and ends after a third or nth signal event (182) which happens at the same rotational position as the first signal event.

摘要： In an electronically commutated motor, both the driving current (i2) and the braking current (i2′) are monitored. When excessive driving current occurs, a pulse duty factor which regulates the current is reduced. When excessive braking current occurs, this pulse duty factor is increased. For this purpose, an analog circuit with two current limiting members is disclosed, as well as a circuit in which these functions are implemented by software in a microcontroller, so that current measurement can be dispensed with. Finally, a combination of these features is disclosed, in which hardware current limitation and software current limitation work together.
