75A, 600V MAGNUM MOTOR DRIVES
DESCRIPTION
The PW-83075P6, PW-84075P6 and PW-85075P6 are half-
bridge drive modules which contain isolated switch drivers, a
pair of solid state switches, an isolated power supply, current
sensing feedback (PW-84075P6 only) and a regenerative clamp
protection circuit (PW-85075P6 only). The three modules can
be used, in any combination, to create drives for brush, brush-
less DC motors or AC induction motors. The logic inputs and
current sense signal are compatible with DSP/microprocessors
and/or FPGA/ASIC circuits used to control the motor drives.
These modular drives are capable of operating from either
±135Vdc or 270Vdc power source that is totally isolated from
the logic input signals. The modules are fault tolerant from out-
put shorts, loss of any or all power supplies and power supply
sequencing.
APPLICATIONS
The high reliability and flexibility of these drives make them suit-
able for Military and Aerospace applications. Among the many
applications are: actuator systems for primary and secondary
flight controls on aircraft; fan and compressor motor drives for
environmental conditioning; pump motors for fuel and hydraulic
fluid; antenna and radar positioning; and thrust vector position
control of missiles, drones, and RPV’s.
