Nidec Servo KV42 and KF42 Hybrid stepper motors

Nidec Servo introduced their new Nema17 sized bipolar (Flange=42mm) stepper motor family under the product code KV42 and KF42. 

With the KV42 and KF42 Nidec Servo (represented by Dynetics) has increased their family of Hybrid-stepper motors with an angle of step of 1,8°. Thanks to the optimized design of the rotor, the supplier managed to realize a more compact size of the motor.  Compared with equivalent type of stepper motors in the industry, both families of the improved stepper motors enable them to realize a much higher performance within a more compact housing. 

Instead of the previous length of 48 mm these motors only show a length of 42 mm. The motors with previous length of 42mm are reduced to 39mm, etc. The KF42 even realizes a higher torque-level.

Further advantages are:

  • Higher maximum torque 
  • Higher stall torque 
  • Higher speed
  • Minimum level of noise
  • Precision windings, outstanding stiffness
  • Improved dynamics
  • 5 different sizes

With these upgrades, the stepper motor family KV42 and KF42 show the highest level of power density in their class. The motors are available with connector or free cable ends. At customers request the supplier also accepts different mechanical upgrades.

Choosing the right fan or blower

Many devices with electronic components deliver more power and have ever higher packing densities. Convection cooling is the most widely used solution, and the most cost-effective method, using air as a medium to dissipate heat by means of forced air movement.
Dynetics, with offices in Germany and the Netherlands, supports developers in selecting the most suitable product for their mechatronic task. For unit cooling without compromise, we have a wide range of axial-, radial, crossflow and centrifugal fans from leading manufacturers

At the upcoming PCIM trade fair, Dynetics will once again present its mechatronic products with Focus on its fans and blowers. Below we list some examples

Auswahl des richtigen Ventilators oder Gebläses:

Viele Geräte mit Elektronikkomponenten bringen immer mehr Leistung und weisen immer höhere Packungsdichten auf. Die Konvektionskühlung ist die am weitesten verbreitete Lösung, und die preiswerteste Methode, wobei Luft als Medium genutzt wird bei der Abführung der Wärme mittels einer forcierten Luftbewegung. Die oft erhöhte Wärmeentwicklung Konvektionskühlung verlangt leistungsfähigere Lüfter, die allerdings auch immer leiser sein sollen.

Dynetics, mit Büros in Deutschland und die Niederlande unterstützt Entwickler bei der Auswahl des für ihre mechatronischen Aufgabe am besten geeignete Bauteile.

Auf der kommenden PCIM-Messe präsentiert Dynetics wieder mechatronischen Produkte mit als Focus seine Lüfter und Gebläse. Unterstehend listen wir einige Beispielen:
