WOUND ROTOR MOTORS

Reuland manufactures a complete line of continuous and intermittent duty wound rotor motors (also known as slip ring motors). Reuland's wound rotor motors provide adjustable speed, starting current, and starting torque.



Continuous duty wound rotor motors are typically either open drip proof or totally enclosed non-ventilated. Intermittent duty wound motors are widely used on crane and hoist applications and are typically 15, 30, and 60-minute duty ratings and provided as open drip proof or totally enclosed non-ventilated. Special custom designed 120-minute or continuous duty wound rotor motors in totally enclosed fan cooled, or auxiliary fan cooled enclosure are also available for refuse or scrap handling cranes.
