    • The acceleration/deceleration control apparatus using slip speed detects an angular frequency ωr corresponding to an execution speed of an induction motor and derives an angular frequency ωs corresponding to a slip speed corresponding to a slip speed in response to a torque of the said motor, from a vector controller of the said motor.
      On the other hand, an allowable value ωs' of said angular frequency corresponding to the said ωr is prepared beforehand, and is compared with said angular frequency ωs.
      According to the result of this comparison, the 1M rotation is controlled. So even if the induction motor is used as servo motor, no shock of the torque will flow through the motor and the motor itself will not be stalled.
    • 使用滑差速度的加减速控制装置检测与感应电动机的执行速度相对应的角频率ωr,并且响应于所述电动机的转矩而导出对应于与滑差速度相对应的滑移速度的角频率ω ,从所述电动机的矢量控制器。 另一方面,预先准备与所述ωr相对应的所述角频率的容许值ωs min,并与所述角频率ωs进行比较。 根据该比较的结果,可以控制IM旋转。 因此,即使将感应电动机用作伺服电机,扭矩的冲击也不会流过电机,电机本身也不会停止。
