High Torque. Built to Last. Made in the USA.

At Square One Electric Motors & Pumps, we supply a full range of Baldor single phase motors, known for their rugged construction, dependable starts, and energy-efficient operation. Designed for use where only single-phase power is available, these motors are ideal for commercial, agricultural, and light industrial applications.

All Baldor motors are brand new, ship directly from the nearest stocked warehouse, and come with a manufacturer’s warranty.

🔧 What Is a Single Phase Motor?

A single phase electric motor is powered by a single alternating current (AC) phase. These motors are commonly used in applications where three-phase power is unavailable or unnecessary, such as on farms, in small shops, residential properties, or rural installations.

Baldor single phase motors are built with a capacitor-start, capacitor-run or split-phase design, offering high starting torque, quiet operation, and low maintenance.

🛠️ Common Applications for Baldor Single Phase Motors

Baldor’s single phase AC motors are a reliable choice for:

• Air compressors

• Pumps (centrifugal, jet, irrigation)

• Conveyor systems

• Grain augers and farm equipment

• HVAC blowers and exhaust fans

• Machine tools

• Food processing equipment

• Sawmills and woodshops

Whether you're powering a pressure washer, a silo unloader, or a belt-driven fan, Baldor motors provide consistent, high-performance output even in tough environments.

Baldor 501 Catalog

If you already have your Baldor catalog number, model number, or frame size, you’re ahead of the game. Use our 🔧 Master Product Search Tool to quickly narrow down Baldor single phase motor options by key specifications:

• Horsepower (HP) – Most common single phase options range from ¼ HP to 10 HP, but we stock a wide variety for both light and heavy-duty applications.

• RPM – Choose between standard motor speeds like 1800 RPM (4-pole) and 3600 RPM (2-pole), depending on your system's torque and speed needs.

• Voltage – Baldor single phase motors are available in 115V, 208-230V, or dual-voltage (115/230V) configurations. Match your voltage to avoid overload or inefficiency.

• Frame Size – Use the NEMA frame number (like 56, 143T, or 184T) from your old motor's nameplate to ensure proper mounting and shaft alignment.

• Enclosure Type – Select based on environment. For indoor or clean settings, use ODP (Open Drip Proof); for outdoor, wet, or dusty conditions, choose TEFC (Totally Enclosed Fan Cooled) or Farm Duty styles.

🛠️ How to Spec Out a Replacement Baldor Motor

If you no longer have the exact motor model or your nameplate is unreadable, follow these steps to determine the correct replacement:

1. Identify the Application: Is the motor used for HVAC, farm equipment, pumps, or shop tools? Load type affects torque and start-up requirements.

2. Check Mounting Style: Look at the base—foot mount, C-face flange, or resilient ring—to ensure a seamless installation.

3. Measure Shaft Size: Match the diameter and length to avoid mechanical mismatches.

4. Note the Duty Cycle: Continuous duty? Intermittent use? Baldor motors are rated accordingly.

5. Confirm Start Method: Choose from capacitor start, split phase, or PSC (Permanent Split Capacitor) motors depending on torque and startup needs.
