Abstract
PURPOSE:To shorten an acceleration or deceleration time, by selecting torque command according to a maximum output pattern when a speed deviation is large, and by selecting torque command according to a rated output specification pattern when the speed deviation is small. CONSTITUTION:The input of a speed deviation C between speed command A and speed detection signal B, to a first torque controlling means L is provided, and the output of torque command D according to a rated output specification pattern is generated from. Besides, the input of the speed deviation C to a second torque controlling means H is provided, and the output of the torque command D according to the maximum output pattern is generated from. The second torque controlling means H is selected by a pattern selecting means P when the speed deviation C is larger than a reference value S, and when the deviation is smaller, the first torque controlling means L is selected. By a current controlling means I, according to a deviation between the torque command D and current signal E, a power controlling means W is controlled.
