摘要： An electric motor (20) has a stator (30) and a rotor (26). The latter is equipped with a cup-like rotor part (56) and with a ring magnet (60) adhesively bonded therein, which magnet has an outer circumference (61) on which are provided elevations (84) and depressions (86) that extend at least partly in the longitudinal direction of the ring magnet (60). The outer circumference (61) of the ring magnet (60), that faces toward the cup-like rotor part (56) after assembly, is formed with at least one opening or channel (68; 69, 88), extending in a circumferential direction, that is connected to at least a plurality of the flat depressions (86). Positive mechanical engagement between adhesive and ring magnet enhances durability, and discourages any tendency toward relative rotation between the magnet (60) and the cup-like rotor part (56).

摘要： A drive circuit for brushless DC motors including a rotor and a stator with at least one stator coil includes a commutation device which supplies commutation pulses of drive current to the stator coil(s). The commutation device senses the rotor position and calculates current rotor speed therefrom. The rotor speed is then used to shift the commutation circuits according to predetermined functions. The shifting of commutation currents is occasioned by shifting either or both of the ignition part of a commutation pulse and the extinction part of such pulse.

摘要： If a motor becomes defective, e.g. stops running, runs too slowly, or becomes too hot, many customers demand the generation of an alarm signal, i.e. ask for an alarm device provided on the motor. The following method is used for configuring this alarm signal: At least one parameter for configuring the alarm device of the motor is inputted via a input interface (80, 82); the at least one parameter is stored in a parameter memory (74; 109); the execution of at least one routine of the alarm device provided in the microprocessor (23) is influenced by said stored parameter or by a parameter derived therefrom. The invention furthermore concerns a motor for carrying out such a method. In a motor of this kind, the alarm device can easily be configured in accordance with a customer's present needs.

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.
摘要翻译：一种改进的电子换向直流电动机整流方法，可以在一个电流脉冲的结束和随后的电流脉冲的开始之间切断电源的施加。根据瞬时转速，可以计算出何时切断电源。在电源中断期间，断开的绕组使用两个MOSFET晶体管在短路模式下工作，并监视电流的衰减。当电流达到预定的减小值时，绕组的端子切换到高电阻状态，直到下一个电流脉冲开始。这具有在操作期间发生较小的无功功率的优点，并且不需要像以前使用的电容器那样安装作为庞大的存储电容器。

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.
