AC Induction and PMAC Motor Controllers

Product catalog summary

Overview
The Curtis 1236 Series motor controllers are designed for AC induction and PMAC motors, offering advanced control features for electric traction and hydraulic pump applications. These controllers are suitable for mobile, on-vehicle applications with a 24-96 VDC nominal battery supply.

Key Features

Increased Performance: Higher peak current ratings allow for smaller, cost-effective controllers. Models are available for 250A–1000A output at 24–96V system voltages.
Advanced Control: Curtis VCL™ allows for custom logic functions, and Field Oriented Control (FOC) algorithms enhance torque and efficiency.
Flexibility: Programmable for traction or pump applications, with field upgradeable software and integrated battery state-of-charge algorithms.
Safety and Reliability: Dual microprocessor architecture ensures high functional safety, with features like reverse polarity protection and thermal cutback.

Specifications

Models: 1232SE, 1234SE, 1236SE, 1238SE
Motor Compatibility: Compatible with AC induction and PMAC motors.
Functional Safety: Designed to meet EN ISO 13849-1 standards, with a focus on preventing uncommanded powered movement and ensuring motor braking torque.

System Accessories

Model 1222: AC induction motor controller for electric power steering systems.
Model 1352: CANbus I/O expansion module with 9 I/O pins.
Model 1313: Handheld programmer for parameter setting and diagnostics.

AC Induction and PMAC Motor Controllers-2

A range of controllers (inverters) for the speed and torque control of 3-phase AC motors. Intended for use as electric traction or hydraulic pump motor controllers for mobile, on-vehicle applications that use a SERIES Logos nominal battery supply. 24-96 VDC The ‘SE’ Advantage The Curtis ‘SE’ AC controllers utilize the latest technology to increase the peak current ratings for each size of controller. For a given rating, the SE models are smaller and lower cost than previous Curtis AC controllers, benefits that are highly advantageous for all types of applications. Only Curtis AC can offer: Curtis...
