41 line encoder ensure the measurement accuracy, which is the revolution of the motor output 41 pulses, pulse shaping is not integrated trigger circuit section motor PCB, so the need to add a comparator circuit or directly in bunches of two resistors (launch European string 390, receive serial 20k), the microcontroller IO port directly, because the resolution is not very high (due to coding is installed in the primary motor, so that the resolution is quite high, and assuming 1:20 deceleration after use, then the reaction on the drive shaft resolution of 20 * 41 = 820 lines), making it ideal for single-chip processing, raster resolution of this motor is very suitable for making the smart car and photoelectric beam stability is high. The following is a DC motor parameters measured by reference. Voltage load current speed stall current 5V, 50mA, 1000 switch, 0.5A 12V, 80mA, 4300 switch, 1.2A 24V, 120mA, 8600 switch, 2.3A 41 line code disc to ensure measurement precision, is the circle motor output 41 pulses, connected to several electronic components can be directly microcontroller IO port, buy motor to send the drawing of electronic components, to send velocimetry procedures, wire feed

The motor according to the number of pulses fed back to precisely control the motor speed, it’s also a great servo motor

Motor 385 motor
Here is my test data

Voltage-load current speed

5V 60mA 1600 rpm

12V 80mA 4300 rpm

24V 120mA 8600 rpm

Code disc grid: 41 lines
