PURPOSE:To rotate an agitator at desired r.p.m. in a specified operating mode by generating a pulse in proportion to the r.p.m. set by an r.p.m. setting dial equipped with a digital display, giving the modalized pulse to a stepping motor and rotating the agitator. CONSTITUTION:A power switch 8 is closed, an operating mode is determined by an operating mode setting device 4 and the r.p.m. is set by an r.p.m. setting dial unit 2. A switch 13 is closed, a pulse is generated from a pulse generator 3 in proportion to the set r.p.m. and an agitator 6 connected to a stepping motor 5 is rotated in accordance with the mode of the operating mode setting device 4. Consequently, the agitator can be rotated at the set r.p.m. in the desired set mode and further the agitator can be slowly rotated at a remarkable low speed. |
