This data sheet discusses and provides some basic formulae to help in selecting a suitable drive motor size. I outlines the requirements for power factor, drive torque, load inertia and duty cycle in the selection process.

• Topics covered -
• Selecting the suitable power rating
• Operating drive torque
• Matching the load inertia
• Analysing torque requirements

The selection of a suitable gearhead is critical to the efficient operation of a drive system. Various models are discussed here enabling an optimum design solution to be achieved. No matter which type of servo gearhead is used, a combination of high dynamic performance and long life can and should be expected. All Mclennan planetary gearheads have the following features -

• High continuous and peak torque ratings for use in applications requiring high repetition rates
• Up to 250% emergency overload capability to protect the gearbox against unusual shock loading
• Exact gear ratios simplify the calibration of positioning systems
• Long maintenance free life of 20,000 hours at full rating
• Easyfit motor mounting system for improved serviceability
• High torsional rigidity for accurate positioning and stable servo control
• Rapid delivery and world-wide service back-up

Finally the selection of an optimum motor and drive combination is discussed, matching the requirements of system speed, operating voltage, load, stability and torque with a suitable control system to give you a reliable and efficient system.
