AC traction controller

12 May 2015

Curtiss-Wright Corporation’s Industrial division has added a new 36V version of the C3 motor controller to its cost-effective range of PG Drives Technology branded AC motor controllers. The new C3-36V is designed for compliance with international floor-care standards – including EN 60335-2-72. 

Operating from a 36V battery supply, the C3-36V is an advanced, compact, AC traction controller for ride-on cleaning machines. Constructed using UL approved materials throughout and designed to comply with UL 583, the controller is equally suitable for other small, ride-on vehicles operating from 36V batteries.

Simple programming enables the C3-36V controller to be compatible with all types of AC induction motors. It also accepts multiple throttle and brake pedal types, including 2- or 3-wire resistive and voltage. CANopen hardware is provided as standard, offering vehicle OEMs maximum input flexibility.

To ensure maximum efficiency, the C3-36V uses an intelligent Hill-Hold function that only takes power from the battery if the vehicle starts to roll. As soon as the system detects that Hill-Hold is not required, no further power is consumed. Traditionally, application of a brake switch has been necessary to provide this function.

The new C3-36V controller uses innovative construction methods to ensure reliable and repeatable assembly of the electronic enclosure, resulting in consistent protection of the electronic circuits from the environment and efficient transfer of heat to the baseplate.
