Magnetically suspended device with function of measuring viscosity |
摘要 |
A rotor is magnetically suspended in liquid by a non-active magnetic bearing with opposed permanent magnets, a step shaped signal at constant voltage is generated from a signal generator, and supplied to an electromagnet of an active magnetic bearing, the response of the rotor at the time is detected by a position sensor, and viscosity equivalent to an damping coefficient is calculated by a CPU.
