Magnetic suspension device for e.g. turbopump, has control unit for controlling temperature of stator coil of electromagnet, and circuit for measuring voltage at terminals of stator coil |
摘要 |
<p>The device has a control unit (30) controlling the temperature of an electromagnet`s stator coil (25). A circuit (28) measures voltage (U) at terminals of the coil, and a determination circuit (31) determines coil`s static current (Io). Determination units are constituted of a divider (33), adding circuits (34, 35) and circuit (36) and determine the temperature from the measured voltage and current and value of electrical resistances (Rc, Ro) of a connecting wire (24) and the coil, respectively. A comparison circuit (37) compares the temperature and maximum admissible temperature (Tmax). An independent claim is also included for a method of controlling temperature of a stator coil.</p> |
