Title:
DRIVE DEVICE AND SPEED COMMAND GENERATING DEVICE
Document Type and Number:
Japanese Patent JP2011002082
Kind Code:
A
Abstract:

To reduce a control error caused by sliding generated on a rolling surface in a drive device which outputs a driving force of a motor via a transmission mechanism which transmits the driving force by friction of the rolling surface between an input rolling element and an output rolling element.

Load torque T transmitted by the transmission mechanism is calculated from an current I supplied to the motor, and a motor rotational speed ω1 (load torque calculation section 30). A slip ratio and a slip velocity slipω1 are determined from the calculated load torque T by using a previously determined relation between the load torque T and the slip ratio slip. The error caused by sliding can be reduced by adding thereof to the target speed command value.
