SX060 Linear servo motor for confined spaces
Nippon Pulse Motor (NPM) has expanded its range of linear servo motors with a very compact version, suitable for applications with confined installation space
As an example, we have realized a reference design for Computerized pipette with 8 individual controllable channels, and is based on the SX060 Linear Servo Motor. The reference design is an example of how we have realized a flexible system with individual reproducible pipetting channels, and enables the automated processing of individual samples from different pipettes quickly, and effortlessly with an optimized throughput. The pipette is user-friendly and very precisely controlled with a compact controller based on FMAX, the Commander hybrid module, and the Arcus CRX-8 driver.
The linear servo motor is a high-precision direct-drive motor.
The linear motor consists of a shaft with rare earth iron-boron-neodymium permanent magnets and a rotor made of cylindrical coil windings.
There is no iron in the shaft or in the driver of the motor, which ensures high precision and cogging-free motors without cogging . The coils themselves form the core and thus give the motor its rigidity. Linear servo motors are contactless. Since the coil completely wraps around the magnets, the magnetic flux density is used effectively. This allows for a large (0.5 to 5 mm) annular nominal air gap. This air gap is not critical, in the sense that there are no changes in force.
This is accompanied by the cylindrical design, through which the copper, the current and the magnetic field generate 100% of the force only in the direction of travel with moderate heat dissipation at the same time. The iron core also provides large absorption forces between the stator and the valve and leads to cogging in linear motion.
No lubrication/adjustment maintenance required
