PURPOSE:To trim a signal being produced when a motor current is converted into a motor control signal. CONSTITUTION:Current flowing through a motor 1 is converted through a converter 2 into an analog signal which is then fed to a rectifying/integrating circuit 3 and sampled at a sample & hold circuit 6 based on a sampling control signal fed from a PWM synchronizing circuit 5 and thus sampled signal is delivered to a motor control processing section 4. |
