DESCRIPTION
The PWR-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 PWR-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 sig-
nal that controls the pulse width modulation (PWM) duty cycle of the
output, thus controlling the motor current. The PWR-82520R can be
tuned by using an external Proportional/Integral (PI) regulator net-
work in conjunction with the internal error amplifier.
•
Holding Torque through Zero Current
•
Cycle-by-Cycle Current Limit
•
Non-Radiation Tolerance also
available (see PWR-82520/21N data
sheet)
APPLICATIONS
The PWR-82520R is ideal for space and radiation tolerant applica-
tions requiring current regulation and/or holding torque at zero input
command. System applications that can use the PWR-82520R are:
pumps, actuators, antenna position, environmental control and reac-
tion/momentum wheel systems using brushless and brush motors.
Available in a 1 and 3 amp small DIP-style or a 10 amp flat-pack
hybrid package, the PWR-82520R is suitable for applications with lim-
ited printed circuit board area.
