Mabuchi FC130SA 334 WIRE AB Phase encoding motor 1.8V-3.3V dc 82ohm
Mabuchi FC130SA encoder tachometer motor encoder 334 line AB phase encoding motor
2: tail with 334 wire AB phase encoder, direct output Fang Bo, do not need to add the circuit, the use of simple, but also the AB phase, can determine the direction of motor rotation, you can do other motor encoder
3: the long axis of the worm, you can drive the worm wheel or changed to elastic or steel coupling (specific look at the following picture)
4: the price is cheap, welcome to wholesale (255 per box, with box as the unit)
The motor's coil DC resistance 30 ohm, the motor operating voltage can be from 3V to 24V. Resistance to turn current = voltage / coil resistance. 12V space and time around the speed of 8200rpm, 24V when the no-load speed of 16800, the speed of the other voltage can be roughly proportional.
Motor tail with the encoder, a total output of two orthogonal (phase difference of 90 degrees) pulse signal. Resolution 334, which means that the motor output of 334 cycles per rotation cycle pulse.
SCM how to determine the direction of rotation?
1: first of all, A or B best to connect the microcontroller interrupt the foot, with the edge of the capture interrupt.
2:A down along when judging the level of the B (or A rising edge when judging the level of B).
The motor features are as follows:
1: Mabuchi motor, micro motor brands, motor is used in the laser printer, industrial quality. Standard models FC130SA, weight is about 20g, containing copper brush (wear long life), exquisite workmanship, varistors, limiting ring copper nylon washer many, specific dimensions, see below pictures.
2:334 line AB phase encoder, containing the shaping circuit, the output is very steep Fang Bo, no overshoot, can be directly linked to the single chip IO.
Level, 3.3-1.5/82=21ma about pressure drop is measured 21ma wave tube are measured 3: the encoder with a normal work (5V suggested by linear voltage regulator chip buck or modify coding circuit transmitting tube current limiting resistor R1, the current 82 in Europe, the circuit is mainly red emission power consumption, it is recommended to use linear voltage regulator chip buck, directly change the current limiting resistance ability strong, otherwise easy to damage), specification, 3.3V power consumption (the main transmitting tube power red LED 1.5V) power after the encoder emits red light, very beautiful, AB phase output in a phase and the B phase of rising or falling edge of the judge each other, we can judge the motor rotation direction.
4: explain the signal line: a phase square wave output, the B phase square wave output VCC, GND is encoder supply must be regulator, voltage range 1.8-3.3v. 5V suggestions with linear voltage regulator chip buck or modify coding circuit on the launch tube current limiting resistor R1, is now 82 euro, circuit is mainly red emission tube power consumption. Motor +, motor - DC motor power supply, voltage range 3-24v, rated 12V, no load current 30-40ma. DC motor power and encoder supply physical completely isolated, then only the encoder power, hand rotating motor, can output AB phase square wave, can not only determine the speed, can also determine the rotation moment direction. With this principle can the motor as the encoder to use, the motor shaft connecting other devices and follow up rotation. And motor, motor voltage range is very wide and divided into positive and negative, polarity, in turn, controlling the motor to rotate reversely, 3-24V can work (the higher the voltage, the faster the rotational speed, or with the PWM duty ratio control, and motor, motor connected with the PWM drive). But the encoder power requirements are high, the requirements of voltage regulators, positive and negative polarity is absolutely not wrong!
5: original with socket, but without line should is the way the FPC connector, but this connector is very expensive, even more than the price of the motor itself, so students do experiments or other general purpose with direct welding line on the PCB (wire attached to the body, prevent to break off). PCB on a number of signal points can be welded, according to their own level of welding to determine the point of welding. 6: if you want to remove the code in addition to use, must have a strong practical ability, some tools and the ability to make special tools, otherwise it is easy to remove the bad. We do not provide dismantling services. About steps are: first fused PCB and motor connected, open coding PCB. Then make special tools (see the following picture on a demo), with pressure under the top disc (definitely not pull hard), in front of the worm if you need to split, with the top of the pressure.
