I'm working on a project where I'll have 3 or 4 servos doing different things. When the program is run the first servo will spin like a winch. When this completes the second servo will lower an arm. The third servo will then begin working until the end.
I have a 30v skytop bench power supply I can set to a constant voltage but my servos are all different.
The first one will likely be a 20 kg servo. Then a. Mg996r. Then the last action is with a 60 kg servo with a recommended voltage of 7.4 v
I'm new at this but do I need to set the bench power to a constant 7.4 volts and then use resisters on the other two servos to lower the voltage? Or would you just let the all run with 7.4 volts even though it might be a bit high for the smaller servos?
Here's the specs
- Operating Speed: 0.17sec / 60 degrees (4.8V no load)
- Operating Speed: 0.13sec / 60 degrees (6.0V no load)
- Stall torque:12kg/cm(6V)
- Operation Voltage : 4.8 - 7.2 V
- Temperature Range: 0℃ to 55℃
- Power Supply: Through External Adapter
20 kg muizei servo
Idle current(at stopped):4mA(5V)/5mA(6.8V)
Operating speed (at no load):0.16 sec/60°(5V)/0.14sec/60°(6.8V)
Stall torque (at locked):18 kg-cm(5V)/21.5 kg-cm(6.8V)
Stall current (at locked):1.8A(5V)/2.2A(6.8V)
Note: 1. The best use voltage is 7.4v.
It is recommended to use 2s battery for power supply (6v-8.4v)
