Engineering Calculating Motor Power Needed to Lift 750kg at 0.3m/sec

Click For Summary
To lift a 750kg load to a height of 20 meters at a speed of 0.3 meters per second, the required motor power can be calculated using the formula for power, which considers both the weight of the load and the height. The horsepower needed is approximately 2.5 HP, factoring in efficiency losses. Additionally, the gear ratio will depend on the motor's RPM and the desired lifting speed; a common approach is to use a gear ratio of around 10:1 for optimal performance. Proper calculations should also account for friction and other mechanical losses. Accurate power and gear ratio specifications are crucial for effective lifting operations.
