Motor driving control apparatus and method, and motor using the same

A motor comprising:

• a motor apparatus including a plurality of coils;
• and
• a motor driving control apparatus controlling current provided to the plurality of coils to control driving of the motor apparatus,
• wherein the motor driving control apparatus includes:
• an inverter unit applying a driving current to the motor apparatus according to a driving control signal;
• a back-electromotive force detecting unit detecting back-electromotive force generated by the driving of the motor apparatus;
• a driving current change unit determining a resistance value using a level of the back-electromotive force and adjusting the driving current with reference to the resistance value;
• and
• a controlling unit performing a control operation to change the driving control signal using the driving current in which the resistance value is reflected and the back-electromotive force.

A motor driving control method performed by a motor driving control apparatus controlling driving of a motor apparatus, the motor driving control method comprising:

• detecting back-electromotive force generated by initial driving of the motor apparatus;
• comparing a level of the back-electromotive force with a preset value and determining a resistance value in inverse proportion to the level of the back-electromotive force when the level of the back-electromotive force is equal to or less than the preset value;
• and
• reflecting the resistance value in the driving current of the motor apparatus and limiting an increase in the driving current at the time of the initial driving of the motor apparatus.
