MOTOR DRIVING CONTROL APPARATUS AND METHOD, AND MOTOR DRIVING SYSTEM USING THE SAME |
| 摘要 |
A motor driving control apparatus may include: a speed estimating unit calculating an estimated speed of a rotor of a motor apparatus by using phase currents flowing in a plurality of phases of the motor apparatus; a speed controlling unit generating an instruction speed by using the estimated speed and a target speed input from the outside; and a control determining unit controlling the motor apparatus to perform one of a sensorless control operation using the instruction speed and a preset synchronous start control operation, depending on whether or not the estimated speed is equal to or less than a preset value. |
