Bias current control circuit |
摘要 |
A control system for a magnetic bearing includes a sensor which generates an output representative of the relative shaft position. The signal from the sensor is processed by an integrator and offset adjustment block and a difference amplifier to subtract the processed sensor signal from a reference voltage. The difference signal result is fed to a bias control circuit including voltage dividers which generates a voltage which is received by coil current power amplifiers for both the upper and lower magnetic coils. Coil currents are then generated to stabilize the magnetic bearing.
