DESCRIPTION
The PW-82520N (100Vdc) and PW-82521N (200Vdc) are high
performance current regulating torque loop controllers designed to
accurately regulate the current in the motor windings of 3-phase
brushless DC and brush DC motors.
The PW-82520/21N is a completely self-contained motor controller
that converts an analog input command signal 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. The current 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 PW-82520/21N perfor-
mance can be tuned by utilizing the internal error amplifier and the
external Proportional/Integral (PI) regulator network components to
match motor characteristics.

APPLICATIONS
The PW-82520/21N is ideal for applications requiring current regula-
tion and/or holding torque at zero input command. System
applications include: pumps, actuators, antenna position,
environmental control, reaction/momentum wheel systems using
brushless and brush motors, flight surface control on aircrafts for
horizontal stabilizers and flaps, missile fin control, fuel and Hydraulic
pumps, radar, and counter measure systems.
Packaged in a small DIP-style hybrid package, the PW-82520/21N is
well suited for applications with limited printed circuit board area.
