The Way of the Future
Curtis AC Induction motor speed controllers represent the next level in
drive systems for material handling and industrial vehicles, offering
lower maintenance, higher performance and greater flexibility. The new
Curtis AC controller family delivers an exceptional level of
sophistication and adaptability for vehicle designers and end-users.
Curtis AC controllers come in compact, fully sealed housings with
advanced thermal management. These controllers combine the renowned
power and smoothness of Curtis speed controllers with a Programmable
Logic Controller to provide rugged strength and unequalled flexibility.
From this powerful fusion came the next evolution in motor speed
controllers - VCL.

1222 |
-
Electric Power Steering
-
24-48V
-
70A
The Curtis Model 1222 is an AC induction motor controller for ‘steer by
wire’ electric power steering systems. In these systems, the steering
motor functions as an actuator to change the angle of the vehicle’s
steered wheel(s) and so change the direction of travel. The Model 1222
performs as the steering system controller, interpreting the steering
command input and wheel position feedback, then driving the steering
motor to move the steered wheel to the desired position. |
Designed for 300–1500W AC induction gearmotors.
Intended applications are materials handling vehicles such as reach
trucks, order pickers, stackers, ‘man up’ warehouse trucks and other
similar industrial vehicles. |

1232 |
-
Traction or Pump
-
24V
-
150-250A
The Curtis Model 1232 provides advanced control of AC induction motors
performing on-vehicle traction drive or hydraulic pump duties. It offers
vehicle developers a highly cost-effective combination of power,
performance and functionality. |
Curtis Model 1232 is designed primarily for Class 3
material handling vehicles, such as walkie pallet trucks. It is equally
suitable for any traction or pump control application. |
|
|
1234 |
-
Traction or Pump
-
24-48V
-
200-350A
Advanced motor drive software provides smooth control over full speed
and torque in all modes, including full regenerative braking, zero
speed, and torque control. Specialized I/O and software features allow
economical and effective control of electromagnetic brakes and hydraulic
systems. |
The Curtis 1234 Motor Speed Controller is designed for
use in all types of electric vehicles including material handling,
industrial, golf, and light-on-road. Generic software and VCL code is
included for control of powered pallet jacks. Other applications can be
easily supported with alternate VCL programming. |

-
Traction or Pump
-
72-96V
-
550-650A
The Curtis Model 1238R provides control of AC induction motors
performing on-vehicle traction drive duties. It offers vehicle
developers a highly cost-effective combination of power, performance and
functionality. |
Designed for use as a traction controller for On-road
electric and hybrid passenger vehicles using 72-96V system voltages, and
other similar applications with low or medium duty cycle. |

|
1298 |
-
Combined AC Traction and DC Pump
-
24V
-
250-300A
This Integrated AC Traction & Hydraulic System controller combines
advanced AC traction motor control with solid state DC hydraulic pump
and proportional valve control to provide a complete economical
intgrated package. |
Primarily for Class III material handling vehicles
requiring variable speed or soft start and stop control of the lift and
lower functions. |
