Title:
DRIVE CIRCUIT OF PULSE MOTOR
Document Type and Number:
Japanese Patent JPS6066697
Kind Code:
A
Abstract:
PURPOSE:To enable to response without vibration nor noise over a wide frequency range by selecting an optimum damper circuit in the drive frequency as to a drive circuit of a pulse motor used for a facsimile. CONSTITUTION:Switching circuit SW1, SW2 are composed of a relay circuit, and the switches are shifted in response to a drive frequency of a motor such as a high speed feeding such as a line skip or a low speed feeding such as a reference mode of a facsimile. In other words, when becoming a high speed responding frequency as the drive pulse is the high speed feeding, induced voltage is fed back to exciting coils L1-L4 through switching resistors R1, R2 to a contact VH. The voltage is switched to a contact VL when the low speed responding frequency range of low speed feeding, and is fed back to the coils L1-L4 without intermediary of the resistors R1, R2.
