IMTS 2012: MCL ironless linear motor moves small masses with precision

IMTS 2012: MCL ironless linear motor moves small masses with precision

The new ironless linear motors by Rexroth position small masses with superior precision and maximum synchronization.

The MCL product line features four sizes with graded lengths and a maximum force range of between 20 and 1,700 newtons. This enables an acceleration of up to 300 m/s² and a maximum speed of up to 1,200 m/min. To increase performance even more, several primary components can be set up in a sequence or parallel to each other. The compact design provides different mounting planes for mounting primary and secondary parts, providing the highest flexibility in construction design.

Optionally, the linear motors also come with a Hall sensor unit to detect the position for the initial commutation.

Compared to ironcore motors, the MCL product line of linear motors distinguish themselves with the ironless design of the primary part, which contains the three-phase winding. The three-phase copper winding is completely compound-filled and not inserted into an iron core. The primary part carrier is made of aluminum and is used to mount the primary component and for heat removal. The U-shaped secondary part contains permanent magnets and encloses the primary component. This design means that slots cannot cause an attraction or cogging force between the primary and secondary part. The force constant is linear due to the eliminated saturation effect. This makes it possible to use compact, cost efficient rail systems.

These aspects combined with the relatively small mass movement by the primary part create a high level of dynamics with a very high degree of precision.

Typical areas in which ironless linear motors can be used are applications where it is important to move small masses at the maximum possible cycle speed with extremely high precision. That includes pick-and-place machines used in general automation processes. The exceptionally high synchronization of the MCL motors also makes them perfect for use in measuring machines.
