Nidec 24H055M020 Brushless DC Motor, 12V, Built-in Driver, PWM Speed Control, 100-Line Encoder

Specification: Note:The red wire is connected to the positive pole, the black wire is connected to the negative pole, the positive and negative poles are strictly forbidden to be reversed, the wrong connection will burn the driver board. Brand new Japanese (Nidec) brushless motor with built-in drive board, with 100 lines of encoder feedback, equivalent to a miniature servo brushless motor, model 24H055M020, it uses imported NSK ball bearings, rare earth medium strong magnetic inner rotor, with pulse frequency regulation (1000HZ-26000HZ range valid), can be forward and reverse, with electronic brake, with full function. Fully functional. Yellow line : PWM, pulse frequency 16000HZ-26000HZ Blue wire :Start/Stop, start when connected to positive terminal, stop when disconnected. White wire :Electronic brake, release when overhanging, brake when connected to GND. Green wire : direction. Steering CW when overhanging, CCW when connected to positive terminal. The other three lines are +3.7V and +3.7V, and the second is the signal output. Black wire: GND Black wire : GND Red wire : +12V (between 10V and 13V) Red wire : +12V (between 10V-13V) Package List: Motor x 1PCS We do not know the correct way to use this motor. We connect the motor according to the above wiring method and the motor runs normally, but as for the wiring of the feedback signal, we do not know it. Please only buy if you know how to use it. Thank you! Motor outer Diameter: 41.9 MM Motor height: 34 MM Motor shaft diameter: 6 MM (with flat position 4.5 MM) Output shaft length: 16.5 MM Motor weight: 118 g Voltage : DC12V Maximum speed : 3900 RPM Cable length : 100 MM (cable is supplied) The red wire is connected to the positive pole, the black wire is connected to the negative pole, the yellow wire is inputted with a pulse frequency of 16000HZ-26000HZ, then the blue wire is connected to the red wire, the motor can be started, it is best to start with the blue wire (start/stop line) the slowest conductive red wire, and stop with the blue wire disconnected as a signal. We power on the machine, think there are a few points need to remind buyers of friends to pay attention to: 1, the positive and negative polarity of the power supply is strictly 1, the positive and negative polarity of the power supply is strictly prohibited to reverse, such as the wrong connection will burn the driver board. 2. The input voltage can only be controlled between DC10V-13V, which is relatively strict, more than this range seems to be unable to start. 3. The direction line (green line) is CW when hanging, CCW when pressing the positive pole, but if CCW is to be selected, the direction line should be connected in parallel to the starter line, and the starter line (blue line) together with the slowest conductor or the first to disconnect. Because the driver board inside seems to be working when the direction wire is powered on. We do not understand what is the reason for this. 4, the yellow line is the pulse frequency must be input to start the motor, pulse frequency between 16000HZ-26000HZ to start the motor. According to our simple wiring method to power on the test machine, with pulse frequency control speed parameters are as follows 1000 HZ 150 rpm 40 MA 10000 HZ 1500 rpm 68 MA 12,000 HZ 1,800 rpm 75 MA 18000 HZ 2700 rpm 96 MA 22000 HZ 3300 rpm 108 MA 26000 HZ 3900 rpm 122 MA As you can see from the data, this is a precision controlled miniature brushless motor, and for every 1000 HZ increase in pulse, the motor speed increases by 150 rpm, which is very precise. As for the feedback line wiring method we do not understand, and we use this method is not completely correct method, we are amateur to the technology, please buyers friends to know their own technology, think it can be used before you can shoot, we are unable to provide technical support. The main point: the red line is connected to the positive pole, the black line is connected to the negative pole, positive and negative pole is strictly prohibited to reverse, reverse will burn the driver board.
