EUCLIDTM AC & DC Controllers for lifting and travel motors on cranes and other motorized equipment.

DC Magnetic Motor Controls

NEMA rated heavy-dutycontrols 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-loadhoisting and lowering.

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.

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

EUCLIDTM AC & DC Bridge Controllers

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.


DC Motor Controllers:

DC constant potential stepped magnetic reversing or reversing/dynamic braking controllers for use with series wound motors.

DC constant potential stepped magnetic controllers for use with shunt wound motors.

EUCLIDTM AC & DC Controller Components

Electronic Frequency Relay

Type 5330

Frequency Relay

Master/slave system designed to be used with wound rotor motor controls. Master unit, which can be used as a stand-alonerelay, is a complete frequency relay providing one point of frequency detection. The slave unit must be used with the master unit and provides additional point of frequency detection. Up to five slave units can be used with each master.

Standard features include:

Green “Relay-on”and red “RelayPicked-up”indicators.

5.5–218hz response range.

Single frequency adjustment set point for each device.

Hand held calibration module to monitor, calibrate or troubleshoot the system.

Static In-LineTimer

Solid state, in-linetiming unit for AC or DC contactor and relay control circuits where a timed “ON” delay is required. Typical application is on crane and mill drives. The timing range is field adjustable by integral potentiometer and ranges from 0.08 seconds to 16.0 seconds, depending on model.
