1. What are Standard Electric Motor Sizes?

Definition: Standard electric motor horsepower (HP) ratings commonly available in the market, typically ranging from fractional to 10 HP.

Purpose: Helps in selecting appropriate motors for various applications based on power requirements.

2. Common Motor Sizes

The most widely available standard motor sizes include:

• 0.5 HP - For light-duty applications
• 1 HP - Common for residential and light commercial use
• 2 HP - Versatile for various mechanical applications
• 5 HP - For heavier industrial equipment
• 10 HP - For large industrial machinery

3. Importance of Standard Sizes

Details: Using standard sizes ensures availability of replacement parts, compatibility with existing systems, and cost-effectiveness.

5. Frequently Asked Questions (FAQ)

Q1: What does HP stand for in motors?
A: HP stands for horsepower, a unit of power equal to 746 watts.

Q2: Can I get motors in sizes between these standards?
A: While custom sizes exist, standard sizes are more cost-effective and readily available.

Q3: How do I choose between 115V and 230V?
A: Depends on your power supply availability and application requirements (higher voltage is more efficient for larger motors).

Q4: What's the difference between T-frame and older frame sizes?
A: T-frame motors (56T, 143T, etc.) are newer standards with different dimensions than older frame numbers.

Q5: Where can I find motors larger than 10 HP?
A: Industrial suppliers carry larger motors, but they typically require three-phase power.
