Radio controlled speed controller with audible feedback signal

摘要: A speed controller with an audible feedback signal capability includes a receiver line, first and second battery lines, motor line. drive circuit is provided for switching between ON state coupling the line to OFF decoupling from Microprocessor circuitry switches according setpoint information received by control connected The microprocessor programmed produce without conventional acoustical transducer cycling at rate controlled period of time duty ratio sufficiently small avoid normal operation so that current flowing during causes audibly discernible mechanical vibration least one circuit, componentry may also turn brake on in order insure path flow apart motor. In above, method producing purposes step providing having as just described. proceeds ratio.
