Electrical measurements

Servo amperage:
Name (amps) [torque]
Hitec HS 50 (0.2) [8.3oz] {smaller than HS55}
Hitec HS 55 (0.19) [15.3oz]
Hitec Digital 5045 (0.28) [13.4oz]
Parallax Futaba S148 (0.56) [?oz uhm, more than those- a standard size servo]

a multimeter hooked in line using a modified servo wire ( red wire cut so the meter could be in line). The servos were operated in their functional duty : Lifting a rocket tube or moving a 4 unit-train of cars. None were 'stalled' so these measurements have only a relative context.


Locomotive Power
an RC ESC only works with a radio, Never mind- it outputs a Voltage Clipped Down from the 7.2 V input battery to whatever level is set for the motor speed.


MRC 9500 (HO train transformer) at about 2 volts
has a voltage spike twice the normal voltage : ? to 'bump' the locomotive? i dunno, it was a SHOCK to see it :(

MRC done again (17 feb) to check various voltage levels. They all have a 'bump' decreasing as the voltage rises to 9 volts... above 9 volts the signal is the same ... a multimeter reads increasing voltages... i dunno what that spike was in the previous view... it looks to be a different time and or voltage amount per grid...

PWM servo signal was of course just spikes of voltage and varying in voltage level, the variation due to the length of the signal variation 'adding' up to different levels i guess

Motor controllers : ? TBD ? investigate the output waveform ... hopefully a level voltage that will change IAW the desired voltage.
