MOTOR SPEED CONTROL
M51971L/FP
MITSUBISHI <CONTROL / DRIVER IC>
How to find rough value of motor transfer
function
(1) Finding K
M
Plot the relation between the motor drive current and tacho-
generator frequency to obtain the inclination.
(2) Finding
ω
M
Though
ω
M
is found by measuring the motor frequency response,
this method generally takes a lot of time and labor. Measurement
of step response can find rough values easily.
Supply step-shape current to the motor in static status, measure
time
τ
M
until the motor speed reaches 63% of the final speed and
then find
ω
M
by the following formula.
