Title:
TORQUE CONTROLLER, DRIVER AND ANTENNA DEVICE
Document Type and Number:
Japanese Patent JP2019080482
Kind Code:
A
Abstract:
To provide a torque controller capable of confining the torque outputted from a motor within a limit range, and to provide a driver and an antenna device.SOLUTION: A torque controller 100 includes two pre-torque generation parts 106A, 106B, two limiter circuits 104A, 104B, and a pre-torque control feedback circuit 107. The pre-torque generation parts 106A, 106B output signals for making two motors generate reverse pre-torque of the same magnitude. The limiter circuits 104A, 104B limit the signals applied to the two motors within a limit range. When the signal applied to one motor exceeds the limit range of the limiter, the pre-torque control feedback circuit 107 reduces torque by negative feedback of the signal that has exceeded the limit range to one pre-torque generation part, and increases torque by positive feedback of the signal that has exceeded the limit range to the other pre-torque generation part.SELECTED DRAWING: Figure 1
