DESCRIPTION
The PW-82520R (100Vdc) is a high performance, radiation tolerant,
current regulating torque loop controller designed to accurately regu-
late the current in the motor windings of 3-phase brushless DC and
brush DC motors.
The PW-82520R 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-82520R perfor-
mance can be tuned by utilizing the internal error amplifier and the
external Proportional/Integral (PI) regulator network components to
match motor characteristics.
Complementary Four-Quadrant
Operation
Holding Torque through Zero Current
Cycle-by-Cycle Current Limit
Non-Radiation Tolerant versions of this
product are also available
(see PW-82520/21N data sheet)
APPLICATIONS
The PW-82520R is ideal for space and radiation tolerant applications
requiring current regulation and/or holding torque at zero input com-
mand. System applications that can use the PW-82520R are: pumps,
actuators, antenna position, environmental control and reaction/
momentum wheel systems using brushless and brush motors.
Available in a 1 and 3 amp small DIP-style and a 10 amp flat-pack
hybrid package, the PW-82520R is suitable for applications with lim-
ited printed circuit board area.
