To buy Money Detector Motor, there is an embodiment of the motor for the new banknote counting machine, including the AC to DC circuit composed of power transformer I, rectifier circuit N, filter circuit in, drive amplifier circuit IV, brake control circuit V, the AC to DC circuit is integrated in a circuit board; 220 v alternating current (ac) after power transformer in turn after ni n I, rectifier circuit, filter circuit is converted into direct current, and the driving amplifier circuit iv amplifier, driven by connected to the amplifier circuit iv on brake control whether the output direct current to the output control circuit v motor, the drive amplifier circuit iv to the motor function, even in the external power supply
Low voltage can also ensure the normal operation of the motor, the whole AC to DC circuit integrated in a circuit board. In the brake control circuit, V adopts TLP521-1 optical chip with high power and small inertia.
Cash counters with the motor on the structure of this practical new type includes a front end cover, bearing, the armature and a permanent magnet, steel pipes, brush, brush, after the end cover and back cover, described set into a cage and formed after the circuit board installed in the rear end cover of space, this structure makes the circuit board to form a organic combination with motor, the circuit board and motor generate electromagnetic fields in relative isolation, Reduce the mutual interference between the two, and make the PCB installation position try to use the existing space in the motor, which is conducive to the miniaturization of the motor. In addition, the steel pipe is coated with silicon steel sheets to prevent sparks.
