Baldor Electric L3509 Capacitor-Start Machinery Motor 1 HP 115/230V AC 56H Frame 3600 RPM

SKU CH-QWKX-226WJ

Single-phase capacitor-start motor delivers 1 HP at 3,600 RPM in a 56H frame for 115/230V AC operation

  • Product typeClosed Base
  • 1 HP capacitor-start motor for high starting torque
  • Dual 115/230V AC input fits common shop wiring
  • 56H frame matches standard mounting dimensions
  • 3600 RPM synchronous speed for direct-drive applications
  • Continuous duty with 1.25 service factor handles sustained loads

Purpose and fit

This Baldor Electric L3509 is a 1 HP single-phase capacitor-start motor built for continuous-duty machinery. It suits workshops and light-industrial equipment that need a standard 56H frame and 3600 RPM output.

Build and connections

The totally enclosed fan-cooled enclosure with a closed base protects windings from dust and debris in typical shop environments. Dual-voltage 115/230V AC wiring and reversible CW/CCW shaft rotation simplify installation on existing mounting patterns.

Upgrade path and limits

It replaces worn capacitor-start units of the same frame, horsepower and speed where a 1.25 service factor and Class B insulation are specified. The motor is not usable at 200V and lacks internal thermal protection, so external overload provision is required.

Questions about this item

What voltage range does the 115/230 V AC motor support, and can it run on 208 V?

The motor is rated for 115/230 V AC and is usable at 208 V, but it is not usable at 200 V.

What frame size and shaft configuration does the 56H frame motor use?

It uses a NEMA 56H frame with a closed base mounting and a standard shaft for CW/CCW rotation.

How do I wire the capacitor-start motor for 115 V versus 230 V operation?

Follow the nameplate wiring diagram to reconnect the dual-voltage leads and the start/run capacitor for the chosen voltage.
