Roller Bearing motor [2]
Just to run an other test upon last weeks video.
A bit higher voltage was used 18 Volts N.L. 10-12 Volts at 170 Amps
The motor accelerates a bit faster but seizes up as the bearings started binding
by the extra current and heat.
When the bearings are very hot the armature doesn't want to turn.
Experiment completed.
Caution !!
Primary Voltage 240V stepped up to 400V by means of a booster TX.
Electricity for the armature is used in this video at low voltages below 42 Volts AC.
