PWR-82520
3-PHASE DC MOTOR TORQUE
CONTROLLER
DESCRIPTION
The PWR-82520 is a high-perfor-
mance current-regulating torque loop
controller. It is designed to accurate-
ly regulate the current in the windings
of 3-phase brushless DC and brush
DC motors.
The PWR-82520 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-82520 can be tuned by using
an external Proportional-Integral (PI)
regulator network in conjunction with
the internal error amplifier.

APPLICATIONS
Packaged in a small DIP-style hybrid,
the PWR-82520 are ideal for applica-
tions with limited printed circuit board
area.
The PWR-82520 is ideal for applica-
tion requiring current regulation
and/or holding torque at zero input
command.
System applications
include flight surface control on air-
craft for horizontal stabilizers and
flaps, missile fin control, fuel and
hydraulic pumps, radar and counter-
measures systems.

How much do you need to learn STM32 to get started? There are too many things I am not used to when switching from 51 to STM32.
From campus study to internship work means a lot of changes. I learned the 51 MCU series on campus, but my internship requires me to learn STM32. The leap is still quite big, and there are too many th...
