Title: Control system for rotary head drum
Inventor: ISHIKURA MASAO
IPC: H04N5/7826
Filed: 1982-03-06
Abstract: PURPOSE:To control a rotary head drum through a simple circuit, by sending out a position detection signal regarding a rotor obtained from the head drum driven directly by a brushless motor synchronously with a speed detection signal, and comparing it with a reference signal and making a correction. CONSTITUTION:A rotor position detector 41 is provided to the brushless motor 40 coupled directly with the drum to output the position detection signal (h). A D-type FF50 clocks the signal (h) by a speed signal S from a tachometer 2 to send an output P to a phase comparator 6. Said output P is compared with the reference signal C to output a signal (d). A frequency discriminator 4 compares the speed signal S with a prescribed frequency to output the difference as a signal Pv. An adder 7 adds the signal (d) and Pv together and the sum signal is amplified by an error voltage amplifier 8 to perform servocontrol over the rotation of the moror 40 through a motor driving amplifier 9. Thus, the speed and phase are controlled accurately by the simple circuit.
