Description
(54) УСТРОЙСТВО ДЛЯ УПРАВЛЕНИЯ МНОГОФАЗНЫМ ЭЛЕКТРОДВИГАТЕЛЕМ(54) DEVICE FOR CONTROLLING MULTI-PHASE ELECTRIC MOTOR
1one
Изобретение относитс к области элект ротехники и может быть использовано дл управлени электрическими машинами.The invention relates to the field of electrical engineering and can be used to control electrical machines.
Известны устройства дл управлени многофазным электроцвигатепем, включаю- щие коммутатор с двум входами, делители частоты, св занные с генератором тактовых импульсов и блок коррекции фазных токов Ш Ш Devices are known for controlling a multiphase electric motor, including a switch with two inputs, frequency dividers associated with a clock generator, and a phase current correction unit.
Однако эти устройства имеют низкийHowever, these devices have low
диапазон регулировани скорости электродвигател .motor speed control range.
Наиболее близким по технической сущности к предложенному вл етс устройств дл управлени многофазным электродвигателем , включающее коммутатор с двум входами, подключенными к генератору тактовых импульсов через делители частоты, счетчик, св занный с одним из делителей и дешифратором, выходы которого подключены на потенциальные входы ключевого блока , выход второго целител св зан с импульсным входом ключевого блока, подключенным выходами поразр дно с входамThe closest in technical essence to the proposed is devices for controlling a multiphase electric motor, including a switch with two inputs connected to a clock pulse generator through frequency dividers, a counter connected to one of the dividers and a decoder whose outputs are connected to potential inputs of the key unit the output of the second healer is connected to the pulse input of the key block, connected to the outputs one by one with the inputs
установки коэффициента делени второго делител частоты 33 .setting the division ratio of the second frequency divider 33.
Однако частота входных команд не может превышать частоту импульсов на выхо- це делителей частоты, так как эта частота используетс в качестве синхронизирующей. Это ограничение существенно при работе электровцигател в диапазоне скоростей, выше скррости приемистости,However, the frequency of the input commands cannot exceed the frequency of the pulses at the output of the frequency dividers, since this frequency is used as a clock. This limitation is significant when the electric scooter operates in the range of speeds, above the pickup rate,
Целью изобретени вл етс расширение диапазона частот ввода информации и рабочих скоростей электродвигател .The aim of the invention is to expand the information input frequency range and motor operating speeds.
