1) After doing the selection of torque/ pressure / displacement of the motor, please retrospectively check whether the working speed is in normal. 2) When the working speed reaches above 80% of rated speed, a motor case flashing circuit should be considered in most applications. 3) The static internal leakage should be considered as the most important safety issue in hoisting applications, thus, the adequate and continuous back pressure should be built in main return line.
Most people have no idea what and how to use a hydraulic motor. Does any other motor supply full torque at stall with no adverse affects? Can you instantly stop and/or reverse direction at full torque? Does size matter? If so, the size to weight ratio can not be beat. Note: that if you increase the torque by going to a larger motor you will decrease the speed.
Hydraulic theory applied with a knowledge of component operation is a lost art in the distribution industry, replaced now by a mentality of part numbers only with no idea of what they represent. Get educated.
Be careful of overall power ratings. Corner horsepower is not necessarily the power level that can be maintained on a continuous basis.
For spindle drive application, make sure that there is enough inertia to avoid stalling of the motor. If required, use a fly-wheel.
Go for standard, reliable makes with service centres available locally with trained technicians.
Try to find and get the best information concerning the application, before buying any type of motors.
Be careful before choosing a motor only because it's cheap- very often you can save money when you spend a bit more at the beginning.
Before buying, arrive to correct torque and speed requirements and keep some cushion and select the motor frame size.
Yes, of course. For customers - to buy good, reputable companies that guarantee the quality of their products.
Create the math model of the load and select the most efficient motor for this application.
Get one that has a long trouble free life span and never over load or over heat them.
No, because every application is unique in my opinion.
Continue & intermittent torque.
