Linear motor accessories

Stators for HIWIN linear motors are available in various lengths. The magnets are cast in epoxy resin to prevent dirt deposits. On request, stainless steel cover plates are available to provide additional protection in environments with high levels of contamination.

The single-part stator covers are available in widths of 3 to 6 for stators of HIWIN linear motors from the LMFA series and consist of a stainless steel cover plate available in customisable lengths and end block sets to clamp the cover plate.

The segmented stator covers are available in sizes 2 to 6 for stators of HIWIN linear motors from the LMFA series. The segments are available in different fixed lengths, which can be connected based on the total length of the stator rod. The cover segments are fixed to the stator by the magnetic force between the cover plates and permanent magnets in the stators.

Since the electrical power is mainly converted in the forcer or primary part of the linear motor and most of the waste heat is generated there, the greatest improvements can be achieved using the precision cooler on the forcer. The precision cooler is assembled on the forcer and integrated into the existing cooling circuit. In order to achieve the best possible effect, the coolant inlet of the precision cooler (forcer) should be connected directly to the coolant outlet of the cooling system of the machine. Likewise, the coolant outlet of the precision cooler should be connected to the coolant inlet of the forcer. This ensures the best possible thermal decoupling and cooling of the linear motor.

Using the stator precision cooler in conjunction with our HIWIN linear motors from the LMFA series and the forcer precision coolers, the thermal decoupling between the linear motor and machine can be improved further. Especially during short stroke applications, the stators also have very high surface temperatures that result in higher temperatures in the working area. The stator coolers counteract this effectively by extracting the heat from the stators and out of the machine via the cooling circuit. Depending on the size, there is either a standard variant that focuses on the best possible cooling performance and, alternatively, a special design for applications that are very difficult to access or where limited space is available.
