Project Planning for Drives Drive selection data 4.2Drive selection data

Certain data is essential to specify the components for your drive precisely. These are:

Determining the motor data It is first necessary to have data on the machine to be driven (mass, speed, settingrange, etc.) to design the drive correctly.These data help determine the required power, torque and speed. Refer to the "DriveEngineering - Practical Implementation, Drive Planning" publication or the PRODRIVEproject planning software for assistance. Selecting the correct drive The appropriate drive can be selected once the power and speed of the drive have beencalculated and with regard to other mechanical requirements.
