Nippon Pulse (www.nipponpulse.com) introduced its latest linear shaft servomotor from the Linear Shaft Motor (LSM) family, the L427 series. It features a five-millimeter air gap between the magnetic shaft and forcer. In the LSM family, the new L427 series offers a low-maintenance linear motion solution with applications in a broad industry range.
With a five millimeter air gap between the motors shaft and forcer, users will have more flexibility machining their device to level. Also, it is a good linear motion solution when users lack the resources or do not have the ability to make an accurate alignment of the shaft and the forcer.
The device is also an optimal motion solution for environments where there is a possibility for debris to stick to and develop on the shaft. If there is a possibility for the debris to develop on the shaft, the five millimeter air gap keeps the motor from jamming and increase the required time between cleanings.
The L427 series features a constant force of 110N and has a useable stroke length between 100 mm and 4,600 mm. The motor’s force constant is 31(Kf) N/Amps, while its peak force is 450N. Other features of the L427 include a 3-kg forcer weight, a 10 V/m/s back EMF, a 14A peak current, a 3.6A continuous current, and a 42.7 mm shaft diameter.
Nippon Pulse’s LSM has three basic concepts. The motor is high precision while giving complete stiffness with its advantageous ironless make-up that offers zero cogging. It is also simple, consisting of only one magnetic shaft and one forcer. And being non-contact, its shaft motor has a non-critical air gap that eliminates force variation throughout the entire stroke of the device.
