The G pole of a field-effect tube can be controlled by the pulse signal whose width can be regulated and which is output by a time-base integrated circuit and an accessory circuit, and the rotation speed of the direct-current dynamo can be controlled by the output pulse of the field-effect tube. The utility model has the advantages of simple device and high reliability, and can be used for various direct-current dynamos.
Description
The utility model relates to the speed regulating device of direct current machine.
Existing dc motor drive has: divider resistance formula, high-power crystal tubular type and stabilized voltage power supply formula, though more than several circuit simple, can waste electric energy because of heating.Can not solve completely for above, but owing to use controllable silicon in DC circuit, control circuit is too complicated by controllable silicon chopper speed control device.
The utility model purpose provides a kind of both energy-conservation, and the control system circuit is simple, and cost is low, the pulsed dc motor drive of dependable performance.
The utility model mainly is to be made of a time-base integrated circuit and field effect transistor and accessory circuit.Charge-discharge circuit cooperates with time-base integrated circuit and produces certain frequency in the accessory circuit, and broad-adjustable pulse control signal goes to control the break-make of field effect transistor.Accessory circuit also is included as and prevents the time-base integrated circuit fault and the fail-safe circuit of output HIGH voltage.
DC motor speed-regulating device provided by the utility model can be used for various direct current machines, has continuously effects such as adjustable, stabilization of speed, economize on electricity.
The drawing explanation: accompanying drawing is the electrical schematic diagram of direct current machine energy-saving speed regulating device.

1Voltage when being lower than 1/3rd supply voltage, time-base integrated circuit pin 7 disconnects capacitor C with ground wire
1The operating state conversion reenters aforesaid charged state, time-base integrated circuit output (the 3rd pin) output high potential.Thereby the output of time-base integrated circuit can with electric capacity discharge and recharge and the output control pulse signal.
When potentiometer W current collector 3 ends to moving to left, the charging interval is long, pulse duration is big, the charging interval that moves right then is short, pulse duration is little, but pulse frequency does not change with moving of potentiometer current collector 3 ends.
When time-base integrated circuit had fault, output was a high potential, made the field effect transistor conducting.In order to make field effect transistor when time-base circuit has fault and end, between the output (the 3rd pin) of time-base integrated circuit and field effect transistor, be provided with partiting dc capacitor C
2, resistance R
1Be that to make the field effect transistor G utmost point be zero potential when not having signal, diode D
1Guarantee that each pulse can both start from scratch.Speed-sensitive switch diode D
2Too high in order to prevent counter electromotive force of motor, stabilized voltage power supply can adopt 7815 integrated regulators, and direct current 15U is provided supply voltage.
