AC Magnetic Motor Controls:
AC controllers for use with new or existing wound rotor or squirrel cage motor drives featuring contactor type secondary control or solid state four quadrant speed regulation. They are ideal for motor primary or secondary controls, eddy current brake hoist, counter torque hoists and life bridge controllers. Also available are adjustable frequency drives. Hubbell AC Motor controllers are designed to meet your specifications and constructed to fit you space.

DC Magnetic Motor Controls:
The most complete line of standard and custom controllers. All controllers are front wired, from connected and front accessible in NEMA rated contactor sizes 0 through 8 for EOT crane control, dynamic lowering and reverse-plugging installations. Also available are mill auxiliary controllers, special circuits to meet custom installation requirements and special construction to meet customer specifications.

AC/DC Solid State Motor Controls:
Hubbell's S²MC Solid State Stepless Motor 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.
Utilizing AC induction motors (squirrel cage and wound rotor) the line of S²MC controllers are available in both primary thyristor (4920 series) and secondary thyristor (4940 series) through 500 hp, or more, and capable of operating on 208/230/380/460/575, 3 phase VAC, 50/60 Hz. The line of S²MC controls have been successfully applied on hundreds of applications for over 15 years.
