DDC is uniquely qualified to support a wide range of application requirements and technologies based upon our decades of experience in analog and digital microelectronics, magnetics, power supplies, radiation mitigation technology and top quality certifications for AS9100 Rev C, ISO 9001:2008, EN9100, JIS Q9100 and through the DLA MIL-PRF-38534.
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 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.
