Excitation controller for an electrical motor, comprises data entry device for acquiring rotational angle, memory for storing control data and controller that receives values for causing first and second torque values

摘要

The controller uses first and second control values to determine a target torque. The ratio of the second control data value is a first deviation between the first and target torques, to a second deviation between the target torque and the second torque values. An excitation controller for an electrical motor has a data entry device for acquiring the rotational angle of the motor rotor. A memory stores control data based on the rotating condition of the rotor. A controller receives first and second control values for causing first and second torque values, where the first torque is larger than the second. First and second control values determine a target torque, where the ratio of the second control data value is a first deviation between the first and target torques, to a second deviation between the target torque and the second torque values.
