Application Note: Advantages of coupling of linear motors

Does your machine need a power upgrade or do you want to expand an existing design?  Coupling two linear motors is an easy and effective way of increasing the available force.  Herewith you are not just limited to using identical motors.  Various combinations can be made, as long as the motor force constant is the same.  This Application Note discusses some details of a ‘coupled application’.

Advantages of technical solutions like a coupling of motors are usually highly case-specific.  Are you thinking about a solution with either one large motor or a couple of smaller ones?  We have listed some common benefits.

Cost effective

Besides the clear advantages of ‘more force’ in a coupled motors application, there are important cost and logistics advantages. Keeping inventory of a similar coil assembly in stock for multiple machines and applications reduces cost and filed support issues. Existing designs can have multiple force capabilities standardizing on existing parts. As linear motor cost is a function of magnet size using dual coils of a smaller motor significantly adds value. This advantage becomes more apparent for longer magnet tracks.

Possible Couplings

Though the motors always have to be connected to a drive in parallel, mechanically it is possible to align them in series or parallel. Motors can move on different magnet tracks to provide even force to a larger gantry or move on the same magnet track to improve the force in one line. In both cases the total force of all motors equals the sum of individual forces.

Do you know the difference between these 10 types of servomotors?

Servomotors are generally used as a high performance alternative to the stepper motor. Stepper motors have some inherent ability to control position, as they have built-in output steps. This often allows them to be used as an open-loop position control, without any feedback encoder, as their drive signal specifies the number of steps of movement to rotate. This lack of feedback though limits their performance, as the stepper motor can only drive a load that is well within its capacity, otherwise missed steps under load may lead to positioning errors. The encoder and controller of a servomotor are an additional cost, but they optimize the performance of the overall system (for all of speed, power and accuracy) relative to the capacity of the basic motor. With larger systems, where a powerful motor represents an increasing proportion of the system cost, servomotors have the advantage….

New TM12 Iron Core Linear Motor by Tecnotion BV

Almelo, Netherlands – The rare earths present in the permanent magnets of linear motors are a cost-intensive factor.  Against this background, the linear motor specialist Tecnotion expands its product portfolio with a new iron core motor: the TM12 is the third in the TM series, producing the same force as motors containing larger, more expensive magnets.

Tecnotion TM12 Iron Core Linear Motor

Tecnotion TM12 Iron Core Linear Motor

With the addition of the TM12 even applications which require the force from larger motor series are now covered by this new motor.  These applications no longer need wider and therefore more expensive magnet plates.

With the 241mm long coil unit of the TM12, a continuous force of 240N and an ultimate force of 480N can be achieved.  In addition, there is the possibility to couple two motors on the magnet track, which increases the available continuous power to 480N.  The dimensions of the motor are compact: the total installation height including magnet plate is only 40mm, the width of the magnet plate is only 50mm. Speeds of 10 m/s are possible.

Especially in applications with long strokes that require long magnet tracks the TM12 represents a cost-effective alternative.  The potential applications are endless: due to the low cogging one can think of use in industrial printers. But machine tooling or cutting systems are also perfect examples where the TM12 can be used.

Understanding the Linear Shaft Servomotor

Nippon Pulse’s Linear Shaft Motor is a brushless, high-precision direct drive linear servo motor with a tubular design.  The motor consists of a magnetic shaft and coil assembly (forcer), and is driven and controlled by the flow of current.

The Linear Shaft Motor can replace ball-screws, pneumatics, U-shaped motors and other linear motion systems.

Design Concepts of the Linear Shaft Motor

  • Simple: Two parts and a non-critical air gap
  • Non-Contact: No wearing and maintenance free
  • High Precision: Ironless design and all the magnetic flux is used

Linear Shaft Motor Specification Overview

  • Variety of shaft diameters, ranging from 4mm to 100mm
  • Stroke lengths of 20mm to 4.6M
  • Achievable peak force of 2340N
  • Maximum continuous force of 585N

Advantages of Linear Shaft Motors

The Linear Shaft Motor is a simple, high-efficiency, high-precision motor that requires no maintenance over its lifetime.  The servo motor consists of only two parts: a magnetic shaft, and a “forcer” of wound coils.  The Linear Shaft Motor offers ultra-high precision because it has no iron in the forcer or shaft, giving you the precision and zero cogging expected in a coreless design while providing the stiffness expected in an iron-core motor.

Because the forcer coil completely wraps around the shaft’s internal magnets, all the motor’s magnetic flux is efficiently used. This allows for a 0.5mm to 2.5mm nominal annular air gap between the shaft and forcer.  This air gap is non-critical, meaning there is no variation in force as the gap changes over the stroke length of the device.

Nippon Pulse’s Linear Shaft Motor can be used in a variety of applications, including pick-and-place machines and dispensing machines.  Applications that require smooth, precise movements and high accuracy will benefit from the Linear Shaft Motor.  If your application has varying force requirements or low-power/high-efficiency requirements, contact an applications engineer to learn how your application can benefit from the Linear Shaft Motor servomotor.

Applications of the Linear Shaft Motor (LSM)

  • High-speed pick-and-place machines
  • High-accuracy pick-and-place or dispensing applications
  • Scanners that need smooth and precise movements
  • Long-life and low-maintenance expectations
  • Applications that require low power and high efficiency

Linear Motor vs. Ball Screw

Reprint of a December 2, 2014 Design World White Paper by Danielle Collins

While ironless linear motors have been used in semiconductor and electronic applications for more than a decade, they are still viewed by many designers and OEMs as “niche” products.  But the perception of linear motors as a costly solution for unique applications is slowly changing, as more industries are adopting them as replacements for ball screws in packaging, assembly, and part loading applications.  And while the cost of linear motor technology has dropped over the past decade, the choice between a linear motor and a ball screw must take into account both the application’s performance requirements and the total cost of ownership over the life of the machine or system.  Below are some of the key parameters to consider when comparing and choosing between ball screws and linear motors…
