Description
(54) УСТРОЙСТВО ДЛЯ КОНТРОЛЯ КРУТЯЩЕГО МОМЕНТА НА ВАЛУ ЭЛЕКТРОДВИГАТЕЛЯ(54) DEVICE FOR THE CONTROL OF THE TORQUE ON THE ELECTRIC MOTOR SHAFT
1one
Изобретение относитс к измерительной технике и может быть использовано дл контрол крут щего момента на валу асинхронного электродвигател .5The invention relates to a measurement technique and can be used to control the torque on the shaft of an induction motor .5
Известно устройство дл измерени вращающего момента асинхронного двигател , путем определени угла сдвига фаз во вспомогательной цепи, содержащее логометр, питаемый от 10 ротора испытуемого двигател через контактньле кольца или от вторичной обмотки дифференциального сельсина, вращаемого этим двигателем 1 .A device for measuring the torque of an induction motor is known by determining the phase angle in the auxiliary circuit, which contains a logometer powered by the 10th rotor of the motor under test through a contact ring or from the secondary winding of the differential selsynin rotated by this engine 1.
Однако это устройство не позво- J5 л ет контролировать заданную величину враЩакхдего момента.However, this device does not allow J5 to control the specified value without any time.
Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс устройство 20 дл контрол крут щего момента на валу электродвигател , содержащее включенные в статорную цепь электродвигател трансформатор на хр жени и трансформатор тока, св занный с 25 фазовращателем, и измерительную схему 2.The closest in technical essence and the achieved result to the invention is the device 20 for controlling the torque on the motor shaft, comprising an external stator transformer and a current transformer associated with a 25 phase rotator and measuring circuit 2 included in the motor stator circuit.
Недостатком такого устройства вл етс низка точность контрол заданной величины крут щего момента. ЗОThe disadvantage of such a device is the low accuracy of control of a given torque value. ZO
Цель изобретени - повышение точности контрол .The purpose of the invention is to improve the accuracy of control.
