Abstract
There are provided a motor driving control apparatus, a motor driving control method, and a motor using the same. The motor driving control apparatus includes a controller, a duty ratio calculation unit, and a driving signal generation unit. The controller generates a speed control signal by using at least one of a speed signal of a motor device and a speed command signal input from the outside. The duty ratio calculation unit calculates a duty ratio of the speed control signal. The driving signal generation unit generates a driving control signal for controlling driving of the motor device by using the duty ratio.
Claims15
A motor driving control apparatus comprising:
- a controller generating a speed control signal by using at least one of a speed signal of a motor device and a speed command signal input from the outside;
- a duty ratio calculation unit calculating a duty ratio of the speed control signal;
- and
- a driving signal generation unit generating a driving control signal for controlling driving of the motor device by using the duty ratio.
A motor comprising:
- a motor device rotating by using driving power provided from the outside;
- and
- a motor driving control apparatus controlling driving of the motor device by providing the driving power to the motor device according to a driving control signal,
- wherein the motor driving control apparatus generates the driving control signal by determining a duty ratio of the driving control signal irrespective of a type of the speed control signal.
A motor driving control method performed by a motor driving control apparatus for controlling driving of a motor device, the method comprising:
- converting a speed control signal into a digital value;
- determining a type of the speed control signal according to whether the digitally converted value has been changed within a pre-set reference time;
- and
- calculating a duty ratio from the speed control signal through different methods according to types of the speed control signals.
