Hello,
I´ll be using this motor:
motors
I´ll appreciate if someone could help me put some instructions to build the power supply to drive this servos.
I want to have plenty of power to drive 6 of them...so...
1. The terminal voltage is 60VDC, constant current 3.7A and a peak current of 25.9A for this servos as the posted spec sheet tells...
2. What voltage is the best to drive the motors, should i drive them at 100%, 90% 80% of the terminal voltage? how can i know the best voltage to drive them?
3. After knowing the voltage, i guess i need the amp needed, so i know there has to be 6 times something, as i want to have power for 6 motors, which amperage should i use, the constant current in the specs times 6? should i allow a safety factor?
4. Knowing the voltage and amp needed in the power supply...next i need to calculate the transformer voltage (VAC), how do i do this?
5. Knowing the transformer voltage (VAC) i have to calculate the transformer current and volt amp (VA) rating, so.. how i do this? and should i consider a safety factor?
6. Guess i can choose a toroid transformer now?
7. How do i calculate the capacitor and the bidge?
Best Regards,
Hector

if i were wanting to power 6 of these motors i would build 3 - 500 watt power supplies with 60 volts output each supply. 1 psu per 2 motors
the components are cheaper, more readily available, smaller and a lot lighter in weight.
- 15 amp or better rectifyer bridge, or 4 diodes (mounted on the chassis).
- maybe 20,000 uf at atleast 75vdc capacitors, each supply,
- dc capacitor voltage draining resistor ( 2 watts )
- fused ac inputs (from the mains) and 2 fused dc outputs at 4 amps each
- 2 dc output connectors with leds after the fuses.
- ac power switch per supply
- ac input plug, like the ones for computers, per supply.
- separate ventalated box per supply, ( no fans necessary ).
- all connections made with fastons and crimp eyeletts ( crimpted and soldered )
- 14 gauge red, black and green wire
- heat shrink tubbing in all main power lines ( maybe silicone as well )
there you go, 3 bricks that will probably last for years and years.
