Product Description:

The MLS070S-3A-0450-NN01 is a secondary part for the MLS Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. As a passive reaction rail that mates with an active primary coil, this component contributes the ferromagnetic teeth necessary for thrust generation along a linear track. When installed in a gantry, picker or machining axis, it allows the drive to deliver direct linear motion without rotary-to-linear conversion and improve positional accuracy on production lines.

The component is supplied in motor size 070, a frame width that determines the magnetic surface area available for force production and matches standard MLS primary sections of the same size code. Its pole pitch of 37.5 mm defines the spatial period of the flux pattern and must align with the commutation sequence in the drive controller. A segment length of 0450 millimeters yields twelve pole pairs, allowing modular extension of the travel path. The secondary part weighs 4.2 kg, and its linear density reaches 9.4 kg/m; these values are used to calculate moving mass and servo loop gains during machine tuning. The IP65 enclosure rating indicates complete dust sealing and protection against low-pressure water jets, enabling installation on open machine frames where lubricants or coolants are present.

Mechanical integration is straightforward because the secondary rail is fixed to the machine bed with screws, and its classification as an Open (Kit Motor) element means the iron core is exposed to the primary winding for highest magnetic coupling. A protective layer identified as With Cover Sheet shields the lamination stack from swarf and accidental contact while adding minimal weight. The internal designation S for the secondary motor type denotes the standard force variant within the MLS platform, making the unit interchangeable with other modules of identical size code that follow the same mounting grid and cabling conventions.
