PRELIMINARY
PWR-82521
3-PHASE DC MOTOR TORQUE CONTROLLER
DESCRIPTION
The PWR-82521 is a high perfor-
mance current regulating torque loop
controller. It is designed to accurately
regulate the current in the windings of
3-phase brushless DC and brush DC
motors.
The PWR-82521 is a completely self-
contained motor controller that con-
verts the analog input command sig-
nal into motor current and uses the
signals from Hall-effect sensors in the
motor to commutate the current in the
motor windings. The motor current is
internally sensed and processed into
an analog signal. This signal is
summed together with the command
signal to produce an error signal that
controls the pulse width modulation
(PWM) duty cycle of the output, thus
controlling the motor current. The
PWR-82521 can be tuned by using an
external Proportional-Integral (PI) reg-
ulator network in conjunction with the
internal error amplifier.

APPLICATIONS
Packaged in a small DIP-style hybrid,
the PWR-82521 are ideal for applica-
tions with limited printed circuit board
area.
The PWR-82521 is ideal for applica-
tion requiring current regulation and/or
holding torque at zero input com-
mand. System applications include
flight surface control on aircraft for
horizontal stabilizers and flaps, missile
fin control, fuel and hydraulic pumps,
radar and countermeasures systems.
