Document Type and Number:
WIPO Patent Application WO/2019/186758
Kind Code:
A1
Abstract:
This drive device of an embodiment is provided with: a signal receiving unit 11 for receiving sensor signals output from angle sensors 4u, 4v, 4w; a signal interval calculation unit 12 for calculating a signal interval ΔT between a sensor signal S1 and a sensor signal S2; an output angle calculation unit 13 for calculating an output angle of a PWM signal on the basis of the rotational speed and target torque of a motor 3; an attachment error acquiring unit 14 for acquiring the errors AS_u, AS_v, AS_w of the attachment positions of the respective angle sensors; a timing determination unit 15 for determining the output timing time to of the PWM signal on the basis of the signal interval ΔT, the output angle, and the errors AS_u, AS_v, AS_w; and a motor control unit 16 for outputting the PWM signal when the output timing time to has elapsed after receiving a sensor signal S3.
