Title:
IMAGE FORMING APPARATUS AND MOTOR CONTROL APPARATUS
Document Type and Number:
Japanese Patent JP2007156089
Kind Code:
A
Abstract:
To change the characteristics of a motor at the start of the motor in accordance with necessity.
A CPU 101 in a driving mechanism 100 reads out a start profile corresponding to a start mode from a ROM 102. Then, the CPU 101 supplies a limit signal to a motor driver 106 in accordance with the read start profile. The motor driver 106 specifies the limit value (upper limit value) of a current from the received limit signal and supplies a current according to the limit value to a motor 107. When a large limit value is set to start the motor 107, the motor 107 quickly reaches a rated rotational frequency, but when a low limit value is set to start the motor 107, noise and abrasion can be suppressed.
