Nous fournissons dans notre gamme de produits les moteurs pas-à-pas de type aimant permanent ou de type hybride, qui peuvent être linéaire. Ces deux types de moteur peuvent également être équipés d’un réducteur, et sont personnalisables selon les besoins de votre cahier des charges.
Nous fournissons également les moteurs à courant continu à balais, solution idéale pour des applications nécessitant un faible encombrement et une grande puissance de sortie, ainsi que les moteurs à courant continu sans balais (BLDC), parfaits pour une utilisation en environnement à fortes contraintes, comme par exemple un environnement sensible aux interférence, les équipements alimentés par batterie, et les environnements à hygiène prioritaire (laboratoire, salle blanche, hôpital, …).
Les moteurs pas-à-pas et BLDC ont une électronique personnalisable pour faciliter le développement d’applications, la possibilité d’intégrer des réducteurs et autres options.
Step Motor Types
Which type of step motor do you need? While all step motors can do similar jobs, you will see differences in performance depending on which step motor you choose. The different options also vary according to price. Read on for a quick breakdown of what you can expect from different step motors.
A permanent magnet motor uses magnets powered by electricity to move the motor along each step according to the electrical pulses transmitted by the step controller. It replaces the « teeth » motion action of earlier variable resistance steppers and, therefore, is more efficient and accurate than the VR motor.
The hybrid motor adds the teeth motion action of the VR to the electromagnetic action of the PM, combining the two for added functionality and accuracy. These step motors cost a little more than PM motors, but for jobs requiring the highest performance, the hybrid step motor is definitely the way to go.
PG step motors are permanent magnet motors with a plastic planetary gearbox, which creates a motor with very high torque in a very small size.
These are PM motors with a linear actuator. This setup allows you to convert rotary motion into linear motion, which is good for applications that require linear action as opposed to the rotary motion of DVD players or turntables, for example.
Types of DC Motors
Perhaps DC Motors are what you need. A DC motor is a motor that runs on DC, or direct current, power. This type of motor is often used in small appliances or toys that require motor action. There are two main types of motors that operate on DC power: brush DC (also known as brushed DC) motors, and brushless DC (also known as BLDC) motors.
With a brush DC motor, the action of special contacts known as brushes push against a commutator to supply constant movement when DC power is applied. A brush DC motor is often an economical solution to basic motor needs, providing great power in a small size. However, the problem with such a motor is that the constant action of the brushes on the commutator not only creates friction and sparking, which reduces the top speed of the machine and may pose a danger to sensitive environments, but also causes wear to the brushes, which eventually need to be replaced. If you are using multiple motors for a long-term project, replacement and maintenance can get expensive.
A good solution that retains the effectiveness of a DC motor without the same maintenance problems is the brushless DC motor. With this type of motor, there is no physical commutator and there are no brushes. Like PM motors, brushless DC motors use permanent magnets to move the rotor and generate power. Although these cost a little more than the brush type, there are no brushes to create friction or sparks, allowing a greater top speed. Even more importantly, there are no brushes or commutators to replace. This means that brushless DC motors tend to be much longer lasting and more reliable than their brushed counterparts. If you need hard-working, effective motors that will last for the long-term, you will want to take a look at our BLDC motors.
