Abstract

Provided are an inverter controller and a method for controlling a torque motor. The inverter controller comprises a main circuit, a control circuit and an operating panel, wherein the main circuit comprises a power supply input interface, a rectifying circuit, a filter circuit, a braking circuit, an inverter circuit and a variable-voltage variable-frequency output interface; the control circuit comprises a central processor, an integrated circuit, a base electrode driving circuit, a direct current side voltage collection module, a direct current side current collection module and an alternating current side voltage collection module; the integrated circuit mainly comprises an operational circuit. A software algorithm of the operational circuit is set, so when a torque frequency curve is calculated in the operational circuit, voltage is kept constant, and the purpose of controlling constant torque is realized. The inverter controller can effectively resolve the problem that the torque motor is nonadjustable at the maximum speed of revolution, improves control precision, and meanwhile reduces production cost.

Description

technical field [0001] The invention relates to a frequency conversion controller, in particular to a frequency conversion controller and a method for controlling a torque motor. Background technique [0002] Most of the current wire processing equipment needs to take up the finished product with an I-shaped wheel. In the past, a torque motor was used to drive the I-shaped wheel to take up the wire. After the material has been pre-treated, it needs to be tightened on the I-shaped wheel according to a certain tension requirement. The torque motor drives the winding I-shaped wheel, and the torque motor controller (voltage regulation) device) to set the winding torque, and the driving torque motor maintains the set tension; the winding part is not equipped with a detection device that feeds back the signal of the current tension. However, this method consumes a lot of energy, the maintenance cost of the torque motor and controller is high, and the maximum speed of the motor is...
