Baldor Electric VL3508 3/4 HP 1140 RPM 115/230V 56C TEFC Fan Accessory

SKU CH-CNQM-QFK3R

A 3/4 HP single-phase motor runs at 1140 RPM on 115/230V AC with a 56C frame and totally enclosed fan-cooled design

  • weight45.55
  • typeClosed Base
  • materialHAWA
  • Runs on standard 115/230 V household power
  • Capacitor-start/run design gives strong starting torque
  • Totally enclosed fan-cooled housing protects against dust and moisture
  • Continuous-duty rating at 40 °C ambient temperature
  • Dual-voltage 56C frame fits many replacement applications

Motor for Continuous Duty

The Baldor Electric VL3508 is a single-phase general-purpose motor rated at three-quarter horsepower and 1140 RPM. It suits equipment that demands continuous operation at 40 degrees Celsius maximum ambient temperature with Class F insulation. The capacitor-start/run design delivers reliable torque for industrial and commercial machinery.

Integration Requirements and Clearances

A 56C frame with closed base allows direct coupling to compatible gearboxes or driven loads without extra mounting hardware. Dual-voltage windings at 115 or 230 volts AC simplify wiring into existing 60 Hz supplies, while usability at 208 volts adds flexibility. The totally enclosed fan-cooled enclosure protects internals from dust and moisture, freeing the installer from adding external ventilation.

Upgrade Context and Limits

This unit replaces open or less protected motors where environmental sealing and continuous duty are now required. The jump is worth it when the application runs non-stop at full load amps of 4.2 A and needs CW or CCW rotation without thermal overload protection. It does not serve buyers who need multi-speed operation, 200-volt compatibility, or a motor with built-in thermal protection.

Questions about this item

How long can the motor run continuously at 40 °C ambient before thermal limits are reached?

The motor is rated for continuous duty at up to 40 °C ambient with Class F insulation and no built-in thermal protection, so the limit is the winding temperature rise under full load.

What are the steady-state heat and noise levels when the motor runs at 1140 RPM all day?

The totally enclosed fan-cooled enclosure dissipates heat through the external fan; noise is typical for a 3/4 hp single-phase TEFC unit at 1140 RPM.

Which voltage supply and frame mounting must the installer provide for this 56C motor?

The motor operates on 115/230 V AC single-phase at 60 Hz and mounts to a standard NEMA 56C face with a closed base.
