Engineered with a robust **Cat 103306.00** series frame, this motor delivers a **1/4 horsepower (0.25 HP)** output at a consistent **1725 RPM**, making it ideal for a wide range of industrial, commercial, and specialty equipment needs. Built with Leeson s signature attention to detail, this motor features a **shaded-pole induction design**, ensuring smooth, low-maintenance operation while minimizing energy consumption. Its **S56C frame** provides a sturdy, space-efficient housing that balances durability with compactness, allowing for seamless integration into tight machinery setups without sacrificing performance. The motor s **NEMA Premium efficiency rating** ensures optimal power delivery with reduced heat generation, extending operational lifespan and lowering operational costs. Whether deployed in conveyor systems, small-scale manufacturing equipment, or specialized automation applications, the C4T17NC61A excels in delivering consistent torque and speed, even under variable load conditions. Its **IP44 protection rating** further enhances its suitability for environments with moderate exposure to dust and splashing water, offering added resilience without compromising performance. With a focus on both functionality and longevity, this motor is a dependable choice for engineers and operators seeking a dependable, high-quality electric drive solution.

### **Pros and Cons of buying a Leeson C4T17NC61A (1/4 HP, 1725 RPM, Frame S56C) Motor**

1. **Compact and Lightweight Design** The S56C frame is a smaller, more efficient motor size, making it suitable for applications where space is limited. This can be advantageous in tight installations, such as in small appliances, pumps, or industrial machinery where bulk is a concern.

2. **Standardized Frame Size** The S56C frame is a widely used NEMA standard, meaning replacement parts, bearings, and accessories are readily available. This reduces long-term maintenance costs and ensures compatibility with other compatible equipment.

3. **Reliable Performance for Low-Power Applications** At 1/4 HP (approximately 190 watts), this motor is well-suited for light-duty tasks such as small fans, blowers, compressors, or conveyor systems. It operates at 1725 RPM, which is typical for single-phase motors in residential or light commercial settings.

4. **Cost-Effective for Basic Needs** As a fractional horsepower motor, it is generally more affordable than larger industrial motors. This makes it a practical choice for budget-conscious buyers who do not require high torque or heavy-duty performance.

5. **Single-Phase Operation** Since it is designed for single-phase power (likely 120V or 240V depending on the application), it is easy to install in standard household or small business electrical setups without requiring three-phase power.

6. **Durable Construction** Leeson is a reputable manufacturer known for producing motors with robust build quality. The motor is likely designed to handle continuous operation under normal conditions, provided it is not overloaded.

- Small pumps (e.g., water circulation, irrigation)

- Air handling systems (e.g., exhaust fans, ventilation)

- Light machinery (e.g., mixers, grinders, small conveyors)

- Appliances (e.g., HVAC components, garage door openers)

8. **Ease of Installation** Due to its standard frame size and common mounting options, installation is straightforward for those with basic mechanical skills. It typically comes with mounting holes and may include a shaft extension or coupling points for direct attachment to driven equipment.

1. **Limited Power Output** At only 1/4 HP, this motor is not suitable for heavy-duty tasks. If the application requires significant torque, frequent starts/stops, or high load resistance, this motor may struggle or overheat, leading to premature failure.

2. **No Built-In Overload Protection** Many basic fractional HP motors lack built-in thermal overload protection. If the motor is subjected to overload conditions (e.g., jammed belts, excessive friction), it may burn out without warning. Additional protection devices (such as thermal relays) may be required.

3. **Single-Speed Operation** This motor does not offer variable speed control unless paired with an external variable frequency drive (VFD). If adjustable speed is needed, additional hardware will be necessary, increasing cost and complexity.

4. **Potential for High Maintenance in Harsh Environments** While the S56C frame is durable, exposure to dust, moisture, or corrosive environments without proper sealing (e.g., IP-rated enclosures) can lead to premature wear on bearings, windings, or brushes (if brush-type).

5. **Noise and Vibration** Fractional HP motors can sometimes produce more noise and vibration than larger, industrial-grade motors, especially if the load is not properly balanced or if the motor is old. This may be a concern in applications requiring quiet operation (e.g., residential HVAC systems).

6. **Limited Lifespan Under Heavy Use** Continuous operation at or near full load can reduce the motor s lifespan. If the motor is frequently cycled on/off or operates under high resistance, it may require more frequent maintenance or replacement compared to a heavier-duty motor.

7. **Compatibility Issues with Non-Standard Equipment** While the S56C frame is common, some older or non-standard machines may require custom adapters or modifications to fit. Always verify shaft size, mounting dimensions, and power requirements before purchase.

8. **No Brushless Option (If Brush-Type)** If this motor uses brushes (common in basic fractional HP motors), brush wear over time can lead to reduced efficiency and eventual failure. Brushless DC or AC induction motors (if available) may offer longer lifespan and lower maintenance.

The Leeson C4T17NC61A (1/4 HP, 1725 RPM, S56C frame) is a **practical and cost-effective choice for light-duty applications** where space is limited, and power requirements are modest. It excels in scenarios such as small fans, pumps, or machinery where reliability and affordability are prioritized over high performance. However, it is **not suitable for heavy-duty, high-torque, or continuous high-load applications**, as it lacks the power and robustness of larger industrial motors.

For buyers who need **adjustable speed, overload protection, or operation in harsh environments**, additional components (e.g., VFDs, thermal relays, or sealed enclosures) may be necessary, increasing the overall cost. If the application involves **frequent starts, high resistance, or extreme conditions**, a slightly larger or more specialized motor (e.g., 1/2 HP or NEMA Premium) would be a safer long-term investment.

---

- You need a **small, affordable, and reliable motor** for light-duty tasks (e.g., small fans, pumps, or conveyors).

- The application **does not require high torque or frequent heavy loads**.

- You are working within a **budget-conscious project** and can supplement it with basic protection devices (e.g., thermal overload relay) if needed.

- The **S56C frame compatibility** is confirmed with your equipment, and you have access to replacement parts.

- Your application demands **high torque, variable speed, or continuous heavy-duty operation**.

- The motor will be exposed to **extreme dust, moisture, or corrosive conditions** without proper protection.

- You require **long-term reliability without maintenance** (consider a NEMA Premium or brushless motor instead).

- The shaft size or mounting dimensions **do not match your equipment**, requiring costly modifications.

- For **higher efficiency and energy savings**, look for a **NEMA Premium-rated motor** in a similar frame size.

- If **variable speed is needed**, pair this motor with a **VFD (Variable Frequency Drive)**.

- For **harsh environments**, opt for a motor with an **IP-rated enclosure** (e.g., IP54 or higher).

- If **torque is critical**, consider a **larger motor (e.g., 1/2 HP or 3/4 HP)** to ensure longevity.

In summary, this motor is a **solid choice for basic, low-power needs** but should not be relied upon for demanding applications. Always verify compatibility and operating conditions before purchase.
