Изобретение относитс к электротехнике и может быть использовано дл управлени бесконтактными электродвигател ми посто нного тока.The invention relates to electrical engineering and can be used to control non-contact DC motors.
Известно, что дл повышени энергетических показателей в бесконтактных электродвигател х посто нного тока необходимо добиватьс максимального приближени формы фаз.ного тока к форме фазной индукции 1 .It is known that in order to increase the energy performance in contactless DC motors, it is necessary to achieve a maximum approximation of the form of the phase current to the form of the phase induction 1.
Известно устройство дл управлени бесконтактным двигателем посто нного тока, содержащее коммутатор, к которому подключен двигатель, датчик тока в цепи питани коммутатора и блок релейного включени питани двигател , к которому подсоединен датчик тока. Посредством релейной обратной св зи по току поддерживаетс его среднее значение на заданном уровне в пределах угла коммутации, что приводит к пр моугольной форме фазного тока. При этом ток на частоте регулировани пульсирует междуA device for controlling a non-contact DC motor is known, comprising a switch to which a motor is connected, a current sensor in a switch power supply circuit and a relay power supply unit for a motor to which a current sensor is connected. Through relay current feedback, its average value is maintained at a given level within a switching angle, which leads to a rectangular form of phase current. At the same time, the current at the frequency of regulation pulses between

Однако этому устройству присущи значительные трудности, св занные с регулированием величины тока, так как при этом необходимо пропорционально измен ть верхнее и нижнее значение тока, т.е. уровень включени и отключени реле. При этом релей ный метод регулировани с задан10 ной амплитудой пульсаций тока при- водит к изменению частоты переключени реле в функции скорости вращени и нагрузки двигател . Таким образом , при определенном сочетании However, this device has significant difficulties associated with the regulation of the current, since it is necessary to proportionally change the upper and lower current values, i.e. relay enable and disable level. In this case, the relay control method with a given amplitude of current ripples leads to a change in the switching frequency of the relay as a function of the rotational speed and the load of the engine. Thus, with a certain combination
