White industrial washdown motor with cooling fins and shaft visible

Leeson

Leeson 191558.00 Washdown Motor 1 hp 1750 RPM 208-230/460V AC 56HC Frame

SKU CH-KBEF-6GQ9Y

Three-phase washdown motor delivering 1 hp at 1750 RPM with 208-230/460V AC input and 56HC frame

  • 1 hp washdown motor for wet environments
  • 1750 RPM three-phase speed for steady torque
  • 208-230/460 V AC dual-voltage flexibility
  • 56HC frame fits standard NEMA mounts
  • Totally enclosed fan-cooled design resists contaminants

Washdown Motor for Wet Environments

The Leeson 191558.00 is a 1 hp three-phase AC motor built for washdown duty. Its totally enclosed fan-cooled enclosure protects internal components from water and debris. The 56HC frame fits standard mounting patterns in food processing, packaging, and pharmaceutical equipment. Continuous duty cycle and Class F insulation support steady operation in demanding industrial settings.

Replaces Standard Open Motors in Washdown Zones

This unit upgrades from standard TEFC or open motors that lack washdown-specific sealing and corrosion resistance. The jump is worth it when equipment undergoes regular high-pressure cleaning or operates in humid, caustic environments. Dual-voltage 208-230/460V AC wiring simplifies replacement across North American plant power systems. It is not usable at 200V, so verify supply voltage before installing.

Sustained Load Behaviour in Continuous Duty

Under continuous duty the motor delivers 1750 RPM at 60 Hz with a 1.15 service factor for occasional overload margin. Full-load current draws 3.2 to 3.0 amps at 208-230V or 1.5 amps at 460V. Class F insulation handles maximum ambient temperatures of 40 degrees Celsius without thermal protection, relying on the driven load and airflow for cooling. CW/CCW rotation is field-reversible for application flexibility.

Questions about this item

What are the shaft and frame dimensions for mounting the 56HC frame motor?

The motor uses a NEMA 56HC frame with a 5/8-inch diameter shaft and standard 56C face mounting bolt pattern for direct coupling to pumps or gearboxes.

How should the nine leads be connected for 230 V versus 460 V three-phase supply?

Wire the nine leads in parallel delta for 208-230 V or series delta for 460 V; the nameplate shows 3.2-3.0 A at low voltage and 1.5 A at high voltage.

Which components typically need replacement after extended washdown duty?

The shaft seals and bearings are the primary wear items; the Class F insulation and 1.15 service factor help the windings withstand the 40 °C ambient rating.
