CENTURY
Frequently asked questions
Common questions about CENTURY from 3G Electric.
What types of enclosures are available for CENTURY general-purpose motors?
CENTURY general-purpose AC motors are available in open drip proof (ODP) and totally enclosed air-over (TEAO) enclosures. ODP motors allow airflow through the windings while protecting against falling liquids or particles, suitable for indoor or sheltered locations. TEAO motors are designed for applications where the motor is mounted in the airstream of the driven equipment, such as condenser fans, providing cooling without external ventilation.
What voltage and frequency options do CENTURY three-phase motors support?
CENTURY three-phase ODP motors, such as the model H885L, are rated for 200-230/460V AC at 60 Hz. This dual-voltage configuration allows connection to either 200-230V or 460V supplies by reconfiguring the motor windings. Full load current varies accordingly, e.g., 5.0-5.6 A at low voltage and 2.8 A at high voltage for a 1 1/2 hp motor.
Are CENTURY condenser fan motors available with ECM technology?
Yes, CENTURY offers the Evergreen® OM series of ECM condenser fan motors. These are constant RPM electronically commutated motors in a 48 frame size with a stud mount and TEAO enclosure. They feature rotation selection via quick-connect plugs and include optional hardware for various mounting configurations, making them suitable for retrofit or new HVAC installations.
What accessories does CENTURY provide for motor protection and adaptation?
CENTURY supplies motor rain shields (drip covers) in overall diameters such as 6 in and 6 3/4 in, with bore diameters of 1/2 in and 5/8 in respectively. Shaft adapter kits are available, for example, with a 1/4 in shaft extension diameter and 1 1/2 in length, using a 1/4-20 thread. These accessories help protect motors from moisture and adapt shaft dimensions for coupling.
Can I find replacement brushes for CENTURY DC motors?
Yes, CENTURY offers DC motor brushes, such as part number 16121, which are compatible with specific motor models like Mfr. No. 22230100. These brushes are designed for maintenance and repair of CENTURY DC motors, ensuring continued operation of equipment that relies on DC drive systems.
What is the typical application for CENTURY circulating pump motors?
CENTURY circulating pump motors, like the HW2024B1L, are single-phase, 115V AC, 1/4 hp units with a 48Z frame size. They are commonly used in hydronic heating systems, hot water circulation, and other fluid transfer applications where a compact, reliable motor is needed to drive a pump impeller.
