Tape recorder motor circuit |
摘要 |
A tape recorder motor circuit includes an automatic shutoff circuit and a motor servo circuit formed by a constant current circuit section, a bridge circuit, and an amplifier section. The constant current circuit section is connected to a power source through a switching transistor which is controlled by the automatic shutoff circuit. The amplifier section of the motor servo circuit is connected in a substantially direct manner to the power source, not through the switching transistor.
