Generally used for conveyors, machine tools, hoists or other applications requiring smooth, accurate adjustable-speed capabilities through the use of thyristor-based controls, often with dynamic braking and reversing also required. Usually direct-coupled to driven machinery, with the motor often additionally supported by a base for maximum rigidity. Such motors are also applicable where extremely high starting torque, or high intermittentduty running torques are needed, even if the application may not require adjustable speed.

High-Voltage, SCR-Rated Brush-Type * Permanent Magnet Field * Washdown-Duty Enhancements * C Face With Removable Base * TENV
