Direct Current DesignsHigh-Voltage, SCR-Rated Brush-Type * Permanent Magnet Field * CFace With Removable Base * TEFCGenerally used for conveyors, machine tools, hoists or other applicationsrequiring smooth, accurate adjustable-speed capabilities through the use ofthyristor-based controls, often with dynamic braking and reversing alsorequired. Usually direct-coupled to driven machinery, with the motor oftenadditionally supported by a base for maximum rigidity. Such motors arealso applicable where extremely high starting torque, or high intermittentdutyrunning torques are needed, even if the application may not requireadjustable speed.High-Voltage, SCR-Rated Brush-Type * Permanent Magnet Field *Washdown-Duty Enhancements * C Face With Removable Base *TENVDesigned for extended life on food-processing machines or other highhumidityenvironments where adjustable speed is required.Low-Voltage Brush-Type * Permanent Magnet Field * C Face WithRemovable Base * TENVFor installations operating from battery or solar power, or generator-suppliedlow-voltage DC. One key application is a pump operating off a truckbattery. Like high-voltage counterparts, low-voltage designs provide linearspeed/torque characteristics over their entire speed range, as well asdynamic braking, easy reversing and high torque.-45-
