The indexer is a rotary transmission device with intermittent rotation function. The realization of its own function needs to be completed under the action of the drive source motor. In the initial stage of the selection of the indexer, the speed, position and drive angle of the indexer The factors have been established in advance, then, in the production and use of the implementation, how should the speed of the indexer be mediated?
For the mediation of the indexer speed, it is actually the mediation of the motor speed. Here is the maximum and least range of frequency changes in the range of the "rated power" of the motor used by the indexer. Most of the indexer uses the motor speed mediation method is to use the governor to complete, for the motor, there is always an upper limit to the speed of rotation, and the speed range in use is more low frequency. For example, a 50Hz design motor, the governor reaches full torque at 0.05Hz, then the speed range is 1:1000. Under normal circumstances, the V/F controlled inverter we use is running at 0.05Hz. When the torque is relatively poor, this does not reach the adjustment range of 1:1000.
The indexer includes motors used in other equipment. Below the fundamental frequency is constant torque regulation. From 0 to 50 Hz, the speed can be changed from 0 to 1440 RPM. The speed regulation above the fundamental frequency belongs to the speed regulation of the balance power. In the case of faster speed, the smaller the torque of the motor, the smaller the power of the motor is. Therefore, when the speed is controlled for the indexer According to the actual situation of the use of the motor, combined with the needs of production efficiency to mediate.
