February 23, 2010 - Nippon Pulse has introduced the L427 series, a linear shaft servomotor that features a 5mm air gap between the forcer and magnetic shaft. In the Linear Shaft Motor (LSM) family, the L427 series is a low-maintenance linear motion solution that has applications in a wide industry range.With a 5mm air gap between the motors forcer and shaft, users have more flexibility when machining their device to level. It is also a good motion solution when a user does not have the ability or resources to do an accurate alignment of the forcer and the shaft.The L427 series is an optimal solution in environments where there is the potential for matter to stick to and build up on the shaft.
When there is the potential for debris to build up on the shaft, the 5mm air gap will prevent the motor from jamming and will also increase the time required between cleanings.The L427 features a usable stroke length between 100 and 4,600 millimeters and has a constant force of 110N. The motor’s peak force is 450N, while its force constant is 31(Kf) N/Amps.
Other features of the product include a 42.7 mm shaft diameter, a 3.6A continuous current, a 14A peak current, a 10 V/m/s back EMF, and a 3kg forcer weight.Nippon Pulse’s Linear Shaft Motor has three basic concepts. It is simple, consisting of only a magnetic shaft and a forcer.
The motor is also high precision, taking advantage of its ironless make-up to offer zero cogging, while giving complete stiffness. Being non-contact, the shaft motor has a non-critical air-gap that eliminates variation in force over the entire stroke of the device.
