RS485 Feetech Servo Motor
Feetech showcased industrial-grade servos, enterprise-grade servos recommended for product design applications, RS485 serial port series, TTL serial port series, robotic serial bus servos, and more.
In-depth understanding, can develop RS485 serial port series servo from hardware and software
Using 7075 aluminum alloy shell, 7075 aluminum alloy is a cold-treated forged alloy with high strength, far better than mild steel. 7075 is one of the strongest commercial alloys. It has a compact structure and strong corrosion resistance. It is also the best for aviation and marine plates. The brushless motor is used as the power drive, the brushless motor adopts electronic commutation, the coil does not move, and the magnetic pole rotates. Compared with the brushed motor, it has less brushes, long life and low maintenance cost; low noise and smooth operation; it also greatly reduces the interference of electric sparks on remote control radio equipment. Using steel tooth box, steel rudder. Everyone is familiar with steel materials. Most of the traditional servos are made of aluminum, copper, iron and other materials, and the hardness is definitely not as good as that of steel teeth. However, steel is more difficult to process because of the more difficult processing technology, and the control of the coefficients of the central process and mode will also be more difficult, and the cost will naturally be higher. In addition, the servo outside adopts steel rudder plate. The traditional servo rudder plate or the swing arm and the rudder arm are made of plastic or aluminum metal arms. The disadvantage is that there will be a gap between the gear and the rudder plate after a period of time. Because aluminum is easy to shape and soft, the external force will make the hole of the rudder plate larger and larger. Steel is hard, and it is difficult to process, and some use the method of laser wire cutting, so the processing cost is also higher. In general, the disadvantage of using steel tooth box and steel rudder plate is that the technical level is high and the processing cost will be higher. The advantages are higher strength, higher output torque and longer life.

12-bit non-contact magnetic encoder is used. Compared with the traditional potentiometer, the control angle range is increased to 360 degrees. The accuracy is higher (closer to 4 times), and any angle can be defined as the median. This is in mass production, and the accuracy of the adjustment after installation can be very high. Of course, the life span is basically unlimited because of the non-contact type. The advantages are high precision, large angle, many functions that can be achieved, and long life. The disadvantage is that it is more expensive than potentiometers.
In the past, many traditional PWM servos were purchased outside the control board, because Feetech did not have its own electronic engineering department.
It's different now: the circuit board is now made by Feetech itself, and the electronics and software are done by itself. Form your own core strengths. The functions required by the servo, position feedback, current feedback, voltage feedback, temperature feedback, and overload protection, current protection, torque limit output, motor continuous rotation mode, angle limit, acceleration start and stop, etc. can be realized.
