Dayton 1TRZ9BG 1 hp 3520 RPM 56C 230/460 V AC Brake Motor

SKU CH-CPM9-RBRK5

A 1 hp three-phase brake motor running at 3520 RPM with a 56C frame and dual 230/460 V AC supply for washdown duty

  • TypeBrake Motors
  • 1 hp output with 3520 RPM for high-speed drive
  • Dual 230/460 V AC supply fits multiple plant voltages
  • 56C C-face mount simplifies direct coupling
  • Totally enclosed non-ventilated body resists washdown moisture
  • Continuous duty at 40 °C ambient for steady operation

Three-Phase Brake Motor for Washdown Use

The Dayton 1TRZ9BG is a 1 hp three-phase brake motor rated at 3520 RPM on a 56C frame. It runs on 230/460 V AC at 60/50 Hz with a 1.15 service factor and Class F insulation. The totally enclosed non-ventilated steel housing suits washdown environments where continuous duty is required.

C-Face Rigid Base Installation Notes

Mount the motor horizontally using the C-face rigid base; the shaft rotates CW/CCW as wired. No thermal protection is fitted, so external overload devices must be provided by the installer. Verify that the conduit entries and mounting bolts align with the 56C pattern before tightening, and confirm the brake coil voltage matches the supply.

Pre-Order Electrical and Ambient Checks

Ensure the site can supply 230 V or 460 V three-phase power with 2.5 A or 1.3 A full-load capacity respectively. The maximum ambient temperature is 40 °C; forced ventilation is not available on this enclosure. Check that the driven load does not exceed the 1.15 service factor and that the mounting surface accommodates the rigid base footprint.

Questions about this item

How do I verify the motor is running correctly after installation?

Measure the full-load current at the terminals and confirm it reads 2.5 A on the 230 V connection or 1.3 A on the 460 V connection while the nameplate speed holds at 3520 RPM.

What comes with the 56C frame brake motor and what must I supply separately?

The motor includes the steel 56C C-face rigid base assembly and integral brake; you must provide three-phase 230/460 V AC power, mounting hardware, and any required coupling or pulley.

Which voltage connection should I use for my 230 V or 460 V three-phase supply?

Wire the motor for 230 V AC if your supply is 230 V three-phase, or for 460 V AC if your supply is 460 V three-phase; both voltages are supported on the same nameplate.
