Carriage apparatus, printing apparatus, and control method thereof

A control method of a printing apparatus,

• the printing apparatus comprising:
• a carriage configured to reciprocally move in a predetermined direction;
• a printhead mounted on the carriage;
• a first motor arranged on a side of one end of a range of movement of the carriage and configured to drive the carriage;
• a second motor arranged on a side of the other end of the range of movement of the carriage, and configured to drive the carriage;
• a detection unit configured to detect a position of the carriage with respect to the predetermined direction;
• a control unit configured to generate a first control signal and a second control signal for controlling the first motor and the second motor, respectively, by feeding back a detection result detected by the detection unit;
• a first driving unit configured to drive the first motor based on the first control signal output from the first control unit;
• and
• a second driving unit configured to drive the second motor based on the second control signal output from the second control unit,
• the method comprising:
• generating the first control signal and the second control signal based on a signal of the detection unit in common and phase information of the first motor which indicates position information of a coil of the first motor;
• and
• driving the first motor and the second motor simultaneously with their output power of a rotation being equal to one another, the first motor and the second motor being brushless DC motors having the same kind of driving characteristics.
