Hydraulic motor torque for a home-built flight simulator

Click For Summary

Discussion Overview

The discussion revolves around the requirements for hydraulic motors in a home-built flight simulator, specifically focusing on the torque needed to lift a weight of 1000 lbs and the speed at which the motor should operate to move this weight a specified distance within a set time frame. The conversation includes technical specifications such as RPM, flow rate, and considerations for motor efficiency.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant seeks to determine the torque required for a hydraulic motor to lift 1000 lbs and the necessary speed to move this weight 1 foot in 2 seconds.
  • Another participant inquires about the length of the arm attached to the motor spindle, which is later specified to be 2 feet.
  • A participant suggests that the motor RPM is defined by the time set for the arm's movement and discusses the relationship between power, force, and velocity, noting that actual power requirements depend on various factors including acceleration and efficiency.
  • One participant expresses a desire for a straightforward answer regarding the type of motor to purchase, indicating a lack of expertise in hydraulic machinery.
  • A later post questions the effectiveness of using a lever attached to the motor for lifting heavy loads, proposing that a hydraulic cylinder might be a more practical solution.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best approach to lift the weight or the specifications for the hydraulic motor. There are competing views on the use of a lever versus a hydraulic cylinder, and the discussion remains unresolved regarding the exact requirements for the motor.

Contextual Notes

Limitations include the lack of specific details about the hydraulic system's design, assumptions about motor efficiency, and the need for further clarification on factors affecting power requirements.

I am constructing a home built flight simulator and am using hydraulic motors with a arm attached to the motor spindle for movement. I need to know how much torque I would need in the motor to lift 1000 lbs. Also I need to know how fast the motor should be to move the weight 1 foot in 2 seconds. Thank you in advance

...using hydraulic motors with a arm attached to the motor spindle for movement. I need to know how much torque I would need in the motor to lift 1000 lbs...

How long is the arm?

Also I need to know how fast the motor should be to move the weight 1 foot in 2 seconds.

Best answer I can give with the info provided is...

1 foot in 2 seconds = 6 inches per second.
 
the arm would be 2'
 
what I wanted to know when I asked about the arm moving, I wished to know how powerful a motor I would need to achieve this. ie: rpm, flow rate etc.
 
You have already defined the motor RPM by setting the time for the 2' arm to travel 6"/s.
The flow rate will depend on the motors swept volume.
You can get a lower limit for power from P=Fv (power =force*velocity). Actual Power required will depend on many other factors - required acceleration, motor efficiency, pipe friction, linkage & bearing friction etc etc.
If you provide a dimensioned sketch we may be able to offer further assistance.
 
sorry I am just a pilot. please elaborate on the acceleration, motor efficiency etc, as I just want someone to tell me what kind of motor I should purchase

thank you again in advance
 
I need to know what size and type of hydraulic motor will lift 1000lbs one foot in one second.

I propose to attach a lever to the motor spindle and attach the end of the lever to the object to be lifted

I need to know the rpm required for the motor, the flow rate in gallons per minute and the psi required to drive the motor to meet these specs

thank you in advance
 
I am no expert in hydraulic machinery, but lifting a heavy load with a lever attached to a motor does not seem a very good idea. Wouldn’t it be more straightforward to use a hydraulic cylinder instead?
 
billy joulebi am currently on holidays and awaymfrom the equipment but will answer you on mymreturn
