AC & DC Bridge Controllers

DC Magnetic Motor Controls

NEMA rated heavy-duty controls for travel or hoisting motors. Both types include mill duty

components on a panel that allows front wiring and front component accessibility. NEMA type

1, NEMA type 1A with gasket, and NEMA type 3R enclosures are available.

Travel Control units feature:

• Smooth, responsive acceleration.

• Safe, controlled stopping.

Hoist Control units feature:

• Complete operator control both hoisting and lowering.

• Dynamic braking; no mechanical brake required.

• High speed no-load hoisting and lowering.

AC Static Crane Controls

Solid state stepless controls are ideal for controlling overhauling loads such as lift bridges,

bridge cranes, bucket/grapple cranes, portal/whirly cranes, turbine cranes, tramways, and

coke oven drives. These highly versatile controllers utilize squirrel cage or wound rotor AC

induction motors through 500 hp or more and are available with either primary or secondary

thyristors. They are capable of operating on 208/230/380/460/575, 3 phase VAC, 50/60 hz.

Modular Components:

Hubbell’s modular approach offers functional units that can be integrated into a complete

control system, either new or existing. Available modules include:

• Variable Speed Control • Power Thyristor • Eddy Current Brake

• Tachometer Continuity • Tachometer/Overspeed • TPM Test

AC Magnetic Motor Controls

Euclid AC controllers are for use with new or existing wound rotor or squirrel cage motor drives. Depending on model and type,

they are ideal for motor primary or secondary controls, eddy current brake hoists, counter torque hoists, lift bridges and other large

machines. Designed to take vibration and dirt, there is no sensitive “on-board” computer, and they can be repaired by in plant people.

There is a type for virtually every application:

• Reversing/plugging travel controller

• Dynamic lowering hoist controller

• Mechanical Load brake hoist controller

• Counter torque hoist controller

• Electric load brake hoist controller

• AC hoist controller with compensated DC dynamic lowering

• DC dynamic lowering hoist controller

(advantages of a dc hoist controller on an ac crane)

Crane Protective Panel:

• Overload and under voltage protection on all motors on a crane.

• Overload relays for three motors standard. Protection for additional

motors can be added.

Hubbell offers several different controls for swing, bascule or vertical lift bridges. Type of control is determined by the mechanical

and structural features of the bridge and the number and location of drive motors.

AC Motor Controllers:

• Primary thyristor static reversing for use with would rotor motors.

• Stepped magnetic contactor/resistor for use with wound rotor motors.

• AC Vector controllers for use with squirrel cage motors.

• Manual drum controllers for use with wound rotor motors.

Speed Switches

Speed switches are designed to respond to

overspeed, underspeed or stopped condi-

tions. Typical applications include con-

veyors, motors, generators, fans, pumps

and machine tools. EUCLID can sup-

ply three types: Fluid/eddy current (simi-

lar to the old centrifugal switches but upgraded for

greater accuracy and durability); Light chopping disk with an LED

light source and light sensitive cell; Proximity sensing (a non-contact

technology which requires no physical connection such as input shaft

extension). Cast iron, cast aluminum, brass or fiberglass reinforced poly-

ester enclosures meet NEMA ratings (specific rating varies with model).

Speed Switches and Sensors

Hot Metal, Infrared, Proximity and Optical Detectors and Sensors

Universal Hot Metal Detectors–Sense hot metal objects and

initiate a desired action (shown-right).

• Detects object without physical contact.

• Adjustable temperature range...no need to stock replacement unit

for each temperature.

• Built to meet demanding mill requirements.

• Air purged and air or water cooled lenses available.

• Adjustable response time.

Optical Position Detectors–Continuously detects the presence and position

of hot metal emitting infrared radiation.

• Rotating lens system with infrared sensitive cell.

• Rugged, mill duty scanner enclosure and mounting.

• Easy installation. No electrical scanner phasing required at start-up.

• NEMA 12 enclosed control unit.

• Air cool or water cooled jacket.

Infrared Detectors–Sense hot metallic or non-metallic materials

such as steel, copper glass, ceramics or plastics.

• Precise detection of product leading and trailing edge.

• NEMA 13 cast aluminum enclosure. Rugged. Suitable for mill use.

• Swivel bracket. Easy installation, set-up and maintenance.

• Self test feature operated from remote pushbutton.

Long Range Proximity Sensors–Ideal for mounting flush or

slightly below floor pans, roller tables or other conveyors.

• Sensing ranges from 1.18" (30mm) to 39" (1000mm).

• Detects objects as small as 3/16" (4mm) square.

• AC and DC voltages.

• Minimal misreadings due to sloppy parts placement, material reflectivity

or dirty/contaminated optics.

• Built-in temperature compensation.
