Induction motor control method |
摘要 |
<p>A method for controlling an induction motor comprises determining an input impedance of the motor 10 at an operating point; determining an input electrical power to the motor 10 at the operating point; and estimating a slip or shaft speed of the motor at the operating point from the input impedance and input electrical power. Motor 10 could be used in an electrical power steering system.</p> |
