SUMMARY

The Japan Servo AS27278 motor operates through a specific configuration of terminals on its PCB, including connections to transistors and capacitors. Key terminals include pin 5, which connects directly to the motor winding, and pin 7, which is unconnected. The motor can potentially be powered by DC batteries and controlled via a 2.4 GHz transmitter, although detailed wiring and component specifications are necessary for successful operation. Users are encouraged to refer to the provided link for additional information and resources.

PREREQUISITES

Hello there! I have here a servo motor - Japan Servo AS27278 but don't have any idea about it. I make some researches on uncle Google about this model or kind of motor and fortunately I was redirected in here. Hoping somebody out here on this site knows and have knowledge about this kind and model of motor.
Ok , first of all, It shows on the attached PCB on the motor are terminals: 7 , 5 , H , V , W
My question is, how does this motor works? and how to make this motor run and is it possible to make this motor run with a supply of DC batteries and control it with 2.4 ghz transmitter?

This is how the terminals/pins on the pcb board connected:

Components on the pcb board as you can see on the photos attached here are: 3pcs transistors WI0 0NI , 4pcs ceramic capacitors and 1pc resistor

- the terminal nos. 1 2 3 4 6 8 have no connections/dead
- the terminal/pin no. 7 was connected to the board *** can't see any component on the pcb was connected to pin no.7 ***
- the terminal/pin no. 5 was connected directly to the one wire winding of the motor
- the terminal/pin no. 9 was connected to the 3rd leg/pin or the collector of the HU Transistor **facing the transistor**
- the terminal/pin no.10 was connected to the: C1 , C2 , C3 going to the Emitter leg/pin of HV Transistor
- the terminal/pin no.11 was connected to the: R1 , C1 , C2 , C3 going to the Emitter leg/pin of HV Transistor
- the base leg/pin of the HU Transistor was connected to the: C2 , C3 going to the Emitter leg/pin of HV Transistor
and so on and so on.
