Conveyor Power Equation:
| From: | To: |
The conveyor motor power calculation determines the required power for a belt conveyor system based on tension differences, belt velocity, and system efficiency. This ensures proper motor selection and efficient conveyor operation.
The calculator uses the conveyor power equation:
Where:
Explanation: The equation calculates the net power required by considering the tension difference across the conveyor pulleys, belt speed, and accounting for mechanical losses through efficiency.
Details: Accurate motor power calculation is essential for selecting appropriate motors, preventing under-sizing (causing system failure) or over-sizing (increasing costs and energy consumption), and ensuring reliable conveyor operation.
Tips: Enter tensions in newtons (N), velocity in meters per second (m/s), and efficiency as a decimal between 0 and 1. Ensure T1 is greater than T2 for valid calculation.
Q1: What is the difference between T1 and T2?
A: T1 is the tension on the tight side (pulling side) of the conveyor, while T2 is the tension on the slack side (return side). T1 is always greater than T2.
Q2: How do I determine conveyor efficiency?
A: Efficiency typically ranges from 0.85 to 0.95 for well-maintained systems. Consider factors like bearing friction, gearbox efficiency, and belt flexure losses.
Q3: What safety factors should be applied?
A: Add 10-20% safety margin to the calculated power to account for start-up loads, material surges, and future capacity increases.
Q4: Can this formula be used for inclined conveyors?
A: This formula calculates the power for overcoming friction. For inclined conveyors, additional power for lifting material must be added separately.
Q5: How accurate is this calculation method?
A: This provides a good estimate for basic conveyor systems. Complex systems with multiple drives or special conditions may require more detailed analysis.
