1 HP 50 Hz Brake Motor

The Leeson 113911.00 is a single-phase brake motor rated at 1 HP with a 1425 RPM nameplate speed. It operates on 50 Hz power at 110/220 V and fits a standard 56 frame. The totally enclosed fan cooled design suits continuous duty in industrial machinery requiring rapid stopping.

Voltage and wiring checks

Verify that your supply is 50 Hz and provides either 110 V or 220 V; the motor is not usable at 200 V or 208 V. Confirm the capacitor-start design matches your starter or control circuit. Ensure the 56 frame mounting pattern and shaft dimensions align with your driven equipment before ordering.

Thermals noise and power

Class F insulation and a 1.0 service factor support continuous operation up to a 40 °C ambient temperature. Manual thermal protection requires operator intervention after an overload trip. Full-load current draws 12.8 A at 110 V or 6.4 A at 220 V, and the TEFC enclosure directs cooling air over the frame for steady thermal performance.

Questions about this item

Does the Leeson 113911.00 include the brake assembly or must it be purchased separately?

The motor is listed as a brake motor with a TEFC enclosure, capacitor-start design and manual thermal protection; mounting hardware and any external brake controls are not included and must be sourced separately.

Should I select the 110 V or 220 V connection for a 50 Hz single-phase supply?

The nameplate shows dual-voltage 110/220 V operation with full-load currents of 12.8 A at 110 V and 6.4 A at 220 V; choose the voltage that matches your supply and circuit capacity.

What does the 1425 RPM rating mean when the motor is driving a loaded machine?

At 50 Hz the motor runs at 1425 RPM nameplate speed with a 1.0 service factor, so under full load it will deliver approximately that speed continuously at 40 °C ambient.
