Title: Rotation transmitter
Inventor: MATSUDA ISAO
IPC: F16H1/00
Filed: 1991-09-12
Abstract: PURPOSE:To reduce the number of wiring by providing a pulse amplifier having a distributor for distributing polyphase pulses from outputs of a decoder and a pulse edge detector, and transmitting the pulse by one serial signal. CONSTITUTION:A pulse amplifier 5 receives a signal from a transmitter 64 and detects a timing of sending reference data from a pulse train by a decoder 51. Thus, a reference timing signal is set, and it is decided that the next coming pulse of the pulse train is a UP-phase pulse. On the other hand, a timing is detected at each rise of the pulse train by a pulse edge detector 52, and it is distributed to 6-phase pulses U, UN, VP, VN, WP, WN by a distributor 53. Reference data are generated immediately after a VN-phase pulse is output. However, the data may be generated immediately after other phase pulse is output. Thus, the pulse can be transmitted as a serial signal via one signal line.
