1. What is Conveyor Motor Torque?

Conveyor motor torque is the rotational force required to drive a conveyor system. It determines the motor's ability to start, accelerate, and maintain the conveyor's operational speed under various load conditions.

2. How Does the Calculator Work?

The calculator uses the conveyor torque formula:

Where:

• \( T \) — Torque (lb-ft)
• \( P \) — Power (hp)
• \( RPM \) — Rotational speed (rev/min)
• \( 5252 \) — Conversion constant

Explanation: The formula calculates the torque output based on the motor's power and rotational speed, with 5252 being the conversion factor between horsepower and foot-pounds per minute.

3. Importance of Torque Calculation

Details: Accurate torque calculation is essential for proper motor selection, ensuring the conveyor can handle startup loads, overcome friction, and maintain consistent operation without overloading the motor.

4. Using the Calculator

Tips: Enter power in horsepower (hp) and rotational speed in revolutions per minute (RPM). Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is 5252 used in the formula?
A: 5252 is the conversion constant that relates horsepower (550 ft-lb/sec) to RPM, derived from the relationship between power, torque, and rotational speed.

Q2: What is typical torque range for conveyor motors?
A: Torque requirements vary widely based on conveyor size, load, and application, ranging from a few lb-ft for small conveyors to thousands of lb-ft for heavy industrial systems.

Q3: How does starting torque differ from running torque?
A: Starting torque is typically 150-200% of running torque to overcome static friction and accelerate the system from rest to operating speed.

Q4: What factors affect conveyor torque requirements?
A: Load weight, belt friction, incline angle, acceleration rate, and environmental conditions all impact torque requirements.

Q5: Should safety factors be applied to calculated torque?
A: Yes, typically a safety factor of 1.5-2.0 is applied to account for unexpected loads, wear, and other operational variables.
