Direct-drive motor DDCTRPM series

ACsynchronous400 V

ABB Baldor-Reliance® direct drive motors are synchronous permanent-magnet motors featuring a laminated, finned-frame design that delivers a highly efficient, power-dense solution. With flange mounting dimensions designed to replace right-angle gearboxes and jackshaft installations, they simplify many conventional cooling-tower drivetrains. This same technology is also available in compact, foot-mounted configurations that can replace belt-and-sheave systems where additional vertical space is available. Built on one of the industry’s most rugged motor platforms, Baldor-Reliance direct drive motors are engineered for reliable operation in the hot, humid environments inside cooling towers. Direct drive motors are ideal for cooling towers, air-cooled condensers and air-cooled heat exchangers. High-efficiency, power-dense direct drive design eliminates gearboxes and belts—reducing maintenance while delivering reliable performance in harsh, hot and humid cooling environments. The gearless, beltless design eliminates many of the components most prone to wear, misalignment and lubrication issues, simplifying maintenance and improving long-term reliability. Direct torque transfer improves drivetrain efficiency by reducing mechanical losses, contributing to lower energy use, reduced operating costs and improved sustainability performance. By eliminating gearboxes, belts and couplings, the simplified drivetrain reduces potential failure points, resulting in higher reliability and increased system uptime.
