PWR-82520/21N
3-PHASE DC MOTOR
TORQUE CONTROLLER
DESCRIPTION
The PWR-82520N (100Vdc) and PWR-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.
Completely self-contained, the motor controller 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 PWR-82520/21N can be tuned by using an exter-
nal Proportional/Integral (PI) regulator network in conjunction with the
internal error amplifier.
APPLICATIONS
The PWR-82520/21N is ideal for applications requiring current regu-
lation and/or holding torque at zero input command. System applica-
tions include: pumps, actuators, antenna position, environmental con-
trol, 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 PWR-82520/21N
is well suited for applications with limited printed circuit board area.
