Furthermore, the amplitude of the excitation current is independently variable of the timing and duration of the application of the excitation current to the windings. This allows increased control of the motor and facilitates the operation of the motor at high mechanical and/or electrical speeds. | 2013-05-30 |
20130134919 | MOTOR CONTROL APPARATUS FOR SYNCHRONOUSLY CONTROLLING MASTER AXIS AND SLAVE AXIS - A motor control apparatus for synchronously controlling a master axis motor for driving a master axis and a slave axis motor for driving a slave axis, includes: a master axis position detector which outputs position data of the master axis and a reference signal with a predetermined fixed period; a master axis receiving circuit which receives the position data and the reference signal output from the master axis position detector; a master axis computation circuit which computes a master axis error representing a difference between the position data received by the master axis receiving circuit and the position data acquired at the time of the reception of the reference signal; and a slave axis motor control unit which controls the operation of the slave axis motor by using the master axis error as a command for synchronizing the operation of the master axis motor. | 2013-05-30 |
