Sigmadrive AC Lift Truck Controller Family Launched
New Sigmadrive family of thermally advanced, high efficiency AC Induction and DC motor controllers intended for lift trucks and other similar electric vehicle applications.
Sigmadrive AC Induction Motor Controllers are suitable for all AC motors and employ
real-time, high resolution current measurement combined with advanced flux control
techniques, offering smooth and highly efficient control of vehicle torque and speed.
Insulated Metal Substrate (IMS) technology is fully utilized to provide superior thermal
performance and exceptional reliability. The innovative design eliminates all internal
links and interconnections, and provides integral heat sinking for all components and
terminals. IMS, combined with the latest low-loss MOSFET technology, increases
reliability and efficiency thus enabling Sigmadrive to provide a higher continuous current
and smaller physical size than other controllers of the same power rating.
"The Sigmadrive controller family represents our entry into the materials handling truck
controller market through this highly advanced and elegant design. Sigmadrive offers
vehicle designers many advantages over existing controllers. They're slim in profile and
small in footprint. Importantly, the thermal performance and high efficiency are really
quite remarkable," says Phyllis Abrams, President, PG Drives Technology, Inc.
CANbus communication is standard to allow for safe and reliable vehicle operation. Dual
traction applications for all Sigmadrive variants can be easily configured, by using two
individual traction controllers linked by CANbus. Multiple Sigmadrives can be interfaced
via the CANbus to provide control of all vehicle functions, and also allows direct
interfacing with ancillary products such as the Sigmagauge LCD vehicle display, Sigma
I/O modules, and other third-party equipment to ensure easy system building.
The Sigmadrive AC Induction motor controllers are available now in three frame sizes
for traction and pump applications, at system voltages of 24V-80V and current outputs
from 125-460A rms. Sigmadrive controllers for most DC motor types are also available,
providing traction, pump and power steering assist functions across the same power range
as the AC Induction motor controllers.
