If the top of the casing is bulged or if you measure a capacitance reading outside the 161-193 MFD range with your multimeter

you can dial in precise transitions for energy management systems or industrial dampers

providing superior protection against corrosion and environmental elements in demanding HVACR applications

making it ideal for belt-driven and direct-drive blowers

Nidec-US Motors 1850 Motor 321894-708 If the top of theThe Nidec US Motors 1850 is a heavy duty 1 2 HP AC motor engineered for reliable performance in commercial and industrial HVACR systems. Operating at a synchronous speed of 1725 RPM, this dual voltage 115 230V motor is built on a NEMA 48 frame with a resilient base to effectively dampen vibration and noise in air moving applications. Featuring Class B insulation and a Continuous Air Over (CAO) duty rating, the 1850 utilizes a permanent split capacitor
