Title: Pachinko ball delivery apparatus
Inventor: NOZAKI YOSHIMICHI
IPC: H02P8/14
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To vary the rotary torque of a stepping motor without switching an excitation system and with a simple circuitry. SOLUTION: A stepping motor 11 is driven by a 1-2 phase excitation system with a bipolar type drive circuit 14 to deliver pachinko balls. In the 1-2 phase excitation system, 1 phase excitation and 2 phase excitation are alternately repeated. When a large rotary torque is required (at the start of the motor or at retrial immediately prior to the stopping of the motor), the time ratio of the 1 phase excitation and the 2 phase excitation is switched over to 1:5 for instance to get a longer time of the 2 phase excitation than that of the 1 phase excitation thereby increasing the rotary torque of the stepping motor 11.  On the other hand, in the fixed speed rotation of the motor requiring no large rotary torque, the time ratio of the 1 phase excitation and the 2 phase excitation is switched over to 5:1 for instance, to get a longer time of the 1 phase excitation than that of the 2 phase excitation. Thus, resulting smaller rotary torque can reduce power consumption and the generation of heat.
