Operation

DESCRIPTION

• Holding Torque through Zero Current

• Cycle-by-Cycle Current Limit

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.

• Non-Radiation Tolerant versions of

this product are also available

(see PW-82520/21N data sheet)

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 sig-

nal that controls the pulse width modulation (PWM) duty cycle of the

output, thus controlling the motor current. The PW-82520R perform-

ance 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-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

limited printed circuit board area.
