Rotor position detection method for a brushless motor and device for carrying out the method |
摘要 |
<p>After disconnection from normal control (3) a pulse generator (4) sends positive and negative pulses to a motor winding R. The response currents are measured (5) from voltages (Vpr,Vnr) which appear after a fixed time on a neutral resistor (2) and their difference is calculated. Similar differences are taken for the two other windings (S,T) and the three values are supplied to a calculator (6) which uses stored data to deduce the rotor position Independent claims are made for equipment used with the method</p> |
