PURPOSE:To eliminate impact noise to be generated from a motor at the time of acceleration or deceleration thereof and to realize smooth operation. CONSTITUTION:A slope generating means 2 produces a signal which increases or decreases at a predetermined rate according to an acceleration/deceleration command 1 and thus produced signal is then applied onto a motor speed control means 4 through a buffer means 3 comprising a primary lowpass filter. According to the constitution, a motor 5 can produce torque continuously and can be accelerated or decelerated smoothly. |
