Motors for the Print Industry

The printing press is used in many aspects of modern life today, from books to instruction manuals to use by dates on packaging.

In the printing industry, both electric DC motors and gear motors are used in a variety of applications on motor-powered printing presses.

DC motors are particularly well suited because they allow for fine control of torque and tension across a wide range of speed ranges, as well as several other advantages such as:

•   High torque output
•   High power density
•   Greater stability
•   Smooth and quiet running
•   Durable and efficient
•   Compact designs
•   Cost-effective

DC motors are also extremely durable and require minimal maintenance, resulting in lower costs and downtime. DC motors are used in a wide range of machines and are considered the heart of most presses. DC motors can be used in a variety of applications, including:
 

• Reel feeds

  Reel feeds which enable printing on the roll rather than sheet form are generally powered by DC motors. To ensure constant wrap the torque control is varied and requires a very precise and accurate motor.

• Printing and converting machines

  These require reliable, continuous control and multiple speed variations which is provided by a DC motor.

• Print Couple Drives

  Digital DC drives control the main print axes of offset printing machines. These require accurate speed control, and the digital DC drives are able to offer the high band-width and regenerative control required.

• Folders and collators

  The majority of high-speed presses have at least one folder, which folds the printed pages. These are then run through collators to produce a completed book or newspa-per (for example). Both folders and collators use DC motors.  

Many printing applications use servo motors because they are more efficient and precise than stepper motors and run much more smoothly. A Parvalux DC brushless motor, on the other hand, can be used as an alternative for many servo motor applications, allowing the equipment to print onto unusual and challenging substrates, adjust for errors, and reduce overall wastage, as well as facilitating the introduction of automation into the press.

As print technology has developed, so has the requirement for innovative geared motor drive system designs. Parvalux supplies the printing industry in its many and varied forms.

We produce custom geared motors for manufacturers of equipment used to produce repeatable samples of paints and surface coatings (such as paint colour charts), systems that print directly onto food products and fruit labelling equipment.

Our latest BLx42 motor is designed for the print machinery industry, for more information on the BLx42 range please contact maxon motor Australia tel. +61 2 9457 7477.
