Dayton 1TRZ8 3/4 hp 3500 RPM 230/460V AC Brake Motor

SKU CH-M4HB-KXM30

Three-phase brake motor delivers 3/4 hp at 3500 RPM with 230/460 V AC supply and 56C frame for washdown environments

  • Product typeBrake Motors
  • Three-phase AC power delivers efficient 3/4 hp output
  • 3500 RPM speed suits high-speed machinery applications
  • Dual 230/460 V voltage fits common industrial supplies
  • Totally enclosed non-ventilated frame resists washdown environments
  • C-face rigid base mounting simplifies horizontal installation

Washdown Brake Motor

The Dayton 1TRZ8 is a three-phase brake motor rated at 3/4 hp and 3500 RPM for 230/460V AC supply. It suits food-processing, packaging or pharmaceutical lines that need frequent stops in wet environments.

56C C-Face Mounting

A 56C frame with C-face rigid base bolts directly to gearboxes or pumps without extra adapters. Totally enclosed non-ventilated construction keeps water and chemicals out while continuous duty rating handles non-stop operation.

Replaces Ventilated Motors

The sealed enclosure upgrades open or TEFC units that fail under washdown cycles. The jump is worth it when hose-down cleaning is daily and brake holding torque must stay reliable at 40 °C ambient.

Questions about this item

How does the 40 °C maximum ambient temperature limit continuous operation?

The motor is rated for continuous duty up to 40 °C ambient; above that temperature the insulation class F winding may exceed its thermal limit and the brake coil can overheat.

What heat or noise level should I expect when the motor runs all day at 3500 RPM?

Totally enclosed non-ventilated construction means no fan noise, but the steel frame becomes the only heat path; surface temperature will rise steadily under full 3/4 hp load.

Which starter or drive must I already have to run this 230/460 V three-phase brake motor?

A three-phase magnetic starter or VFD rated for 2.0 A at 230 V or 1.0 A at 460 V with a separate brake-coil supply is required.
