A digital hall sensor for the QTR Series Torque motors. The sensor enables simple commutation of the motors.
Thanks to the digital hall sensor there is no need for costly or complex drives. It allows a quick start up of an application without wake & shake procedures. When it comes to applications which only require basic accuracy or a stable speed, for example in conveyor belts and high speed doors, there is no need for an expensive external sensor at all.
The Digital hall sensor comes in a fully encapsulated housing, featuring an unidirectional cable. The slim housing integrates with bolts on to the torque motor, adding no extra height to the motor. Applications in robotics, packaging and automation can benefit from the unique features of the QTR Digital Hall sensor.
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 anew iron core motor: the TM18 is the fourth in the TM series, producing the same force as motors containing larger, more expensive magnets.
With the addition of the TM18 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 magnetplates.
With the 336mm long coil unit of the TM18, a continuous force of 360N and an ultimate force of 720N can be achieved. In addition, there is the possibility to couple two motors on the magnet track, which increases the available continuous power to 720N. 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 TM18 represents a cost-effective alternative. The potential applications are endless: due to the low cogging one can think of use in industrial printers. But machinetooling or cutting systems are also perfect examples where the TM18 can be used.
Designed and constructed with an iron core, these linear motors offer extremely high continuous force for their size, starting at 60N for the small TM, all the way up to 3000N for the water cooled TBW powerhouse. Peak forces are even higher, reaching up to 6000N.
All this raw power comes in a surprisingly compact package. Its small footprint, modular design and high force density enable very flexible application designs. The ability to string multiple motors together, either in series or parallel, widens its range of applications even further.
Examples of application areas that benefit from the Iron Core series' specific qualities include:
In contrast to iron core motors, these motors feature an ironless coil unit, so there is no attraction force or cogging between the coil unit and the magnet track. This is what gives ironless motors their light weight, superior precision, a linear force constant and extremely dynamic velocity, acceleration and deceleration. Continuous force ranges from 10N all the way up to 846N with peak force of up to 4200N.
The benefits of ironless linear motors are optimal for applications that require small masses to be moved with maximum precision at a high cycle speed, especially in areas like:
A direct sibling of our U-series, these vacuum rated ironless motors feature specifically designed coil units and magnet yokes for use in high vacuum, down to 10-8 mBar.
Apart from the features carried over from our regular ironless motors: light weight and ultra precision, this series is also capable of incredibly smooth motion and achieves the lowest amount of outgassing possible for a series product of this type. The importance of low outgassing can be so crucial for certain applications, that we had this thoroughly tested and can even supply you with exact specifications and performance details, should you so desire.
Thermal management is one of the main challenges inside a vacuum, so we've designed the coil units in such a way as to achieve an extremely low thermal resistance; easily and quickly conducting heat away from the unit. Integrated temperature and cut-off sensors guarantee thermal protection at all times.
Key industries that can benefit from these motors are, for instance:
The challenge in these applications is the unmatched performance the motor needs. These motors are completely designed according the specific application. This requires very close development and engineering cooperation with the customer, and a lot of application knowledge.
This high level of linear motor technology is unique in the world.
Examples of these motors properties and requirements:
Advanced linear motor key competences are:
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.
Horizontal panel beam saws are used in the woodworking industry to cut large sheets, strips, or panels of wood or wood-based materials, such as oriented strand board (OSB), into various sizes. The cuts are made by a circular saw mounted on a traveling carriage, which is normally driven by a brushless motor matched to either a belt drive or rack and pinion system.
Large format printers are used to print all types of large artwork and signage, including banners, wallpaper, vehicle image wraps, architectural drawings, and electronic circuit schematics.
