1-2 phase excitation
③ The reference excitation method is described below.
Method
(3) Driving the bipolar transistor
① Drive the motor by the fixed current control for the output torque stabilization to the applied voltage
change. This reference excitation current is 500mA. Applying any excessive electric current will
cause the abnormal generation and the excessive torque, which will end in mechanical damages;
therefore, do not apply any electric current that exceeds the requirement.
② Determine the motor driving requirements after confirming effects of load variations caused
by temperature, the humidity, and types of paper. If the motor is driven by any excessive
torque, the gears may be damaged when the paper is locked; therefore, attention should be
paid.
