Description
Обычно контроль биени роторов и статоров электрических машин производитс механическим контактным индикатором.Usually, the control of the beats of the rotors and stators of electrical machines is performed by a mechanical contact indicator.
Предложенный прибор вл етс новым и особенность его заключаетс в том, что он выполнен в виде эталонного статора или ротора с измерительной катушкой, расположенной на одном из зубцов пакета эталонного статора при проверке ротора или на одном из зубцов пакета эталонного ротора при проверке статора. Катушка при этом включаетс в мостовую схему с переменными активными сопротивлени ми в . Дл вращени установленного в пэибор провер емого ротора или статора служит особый механизм. Кроме того, прибор может быть использован дл контрол точности скоса пазов в электрическихThe proposed device is new and its feature is that it is made in the form of a reference stator or rotor with a measuring coil located on one of the teeth of the package of the reference stator when checking the rotor or on one of the teeth of the package of the reference rotor when checking the stator. The coil is included in a bridge circuit with variable resistivity bars. A special mechanism serves to rotate the checked rotor or stator installed in the peebor. In addition, the device can be used to control the accuracy of the slope of the slots in electrical
машинах.machines.
Дл определени биени статора и ротора в высокочастотных решаюших машинах механический контактный индикатор не пригоден и предложенный способ пока вл етс единственно известным.To determine the stator and rotor beats in high-frequency solvable machines, the mechanical contact indicator is not suitable and the proposed method is currently only known.
На чертеже схематически изображено предлагаемое устройство дл установки провер емого ротора или статора, которое состоит из неподвижно заКрепленного эталонного ротора / или статора 2, представл ющего собой пакрт магнитоппЪво.та такой же машины с измерительной катушкой 3 (Xi) на одном зубце, и механической части, обеспечивающей установку и вращение провер емого ротора или статора относительно базовой оси.The drawing shows schematically the proposed device for mounting a tested rotor or stator, which consists of a fixedly fixed reference rotor / or stator 2, which is a package of a magnetometer of the same machine with a measuring coil 3 (Xi) on one tooth, and the mechanical part providing installation and rotation of the tested rotor or stator relative to the base axis.
