ya. the coil is connected to a 3 phases motor. and act as a brake for the motor...
Is the coil in such a position that it is electromagnetically coupled to the 3 phase motor winding.? In other words is it designed to pickup the field from the motor.?
what the meaning about unipolar or bipolar depending on its construction?
explain further pls..... thx
Unipolar is when the coil is designed and positioned to pickup and output a pulse that goes from 0V to a +V [or -V], one direction, a halfwave cycle,
Bipolar is when the picked up pulse goes to +V and then down thru 0V and to a -V.. A fullwave cycle
im using a digital multimeter...... boths also giving reading ( standstill ).
ya. both...... 130 VDC+/- and 100 VAC+/-........... and the resistance for the coil about 0.46 ohm +/-.....
A half cycle pulse will give a ac and a dc reading on a DMM.
Your 130Vdc and 100Vac suggest that its a positive goind unipolar pulse ocurring every half cycle.
are R1 and R6 resonantor..............
Do you mean resistor.?
all experts are welcome.......
