インバータ装置
Document Type and Number:
Japanese Patent JP6699241
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an inverter device capable of measuring the number of pulses outputted from a pulse encoder per one rotation of a rotary electric machine with accuracy.SOLUTION: An inverter device 100 comprises: a pulse counter 6 that receives pulses from a pulse encoder 206 provided at an outer periphery of a motor 200 having a permanent magnet; a PWM signal generation unit 3 that outputs a current for driving the motor 200; and a pulse number calculation unit 7 that calculates the number of pulses outputted from the pulse encoder 206 per one rotation of the motor 200 on the basis of a cycle of the current for driving the motor 200 outputted from the PWM signal generation unit 3, and the number of counter electrodes of the motor 200.SELECTED DRAWING: Figure 2
