| 发明名称 | Systems and methods for controlling high speed motor | ||
| 摘要 | A method for controlling an electric motor includes inputting a quadrature-axis current (Iq) and a direct-axis current (Id) into an electric motor, receiving speed feedback indicative of the speed of the electric motor, determining whether the speed of the electric motor increases given the input Iq, and controlling the Id to increase the speed of the electric motor by selectively weakening the electromagnetic field if the speed of the electric motor does not increase given the input Iq. | ||

| 主权项 | 1. A method for controlling an electric motor, comprising: inputting a quadrature-axis current (Iq) and a direct-axis current (Id) into an electric motor; receiving speed feedback indicative of the speed of the electric motor; determining whether the speed of the electric motor increases given the input Iq; and controlling the Id to increase the speed of the electric motor by selectively weakening the electromagnetic field if the speed of the electric motor does not increase given the input Iq; and reducing the Iq by a first increment until a drop in the speed of the electric motor is received if the speed of the electric motor does not increase with the input of the Iq and before controlling the Id to increase the speed of the motor. | ||
