TM AC & Dc controllers forlifting and travel motors on industrial cranes and othermotorized equipment.
NEMArated heavy-duty controls for travel or hoisting motors. Both types include mill dutycomponents on a panel that allows front wiring and front component accessibility. NEMAtype
1, NEMAtype 1Awith gasket, and NEMAtype 3R
industrial enclosures are available. Travel Control units feature: Hoist Control units feature: ? Smooth, responsive acceleration.
? Safe, controlled stopping. ? Complete operator control both hoisting and lowering.
? Dynamic braking; no
mechanical brake required.
? High speed no-load hoisting 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
industrial hoists, counter torque hoists, lift bridges and other largemachines. 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 mechanicaland structural features of the bridge and the number and location of
drive motors.
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. AC MotorControllers: ModularComponents: ? 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. 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
