Product Description:

The MLP070A-0150-FS-N0CN-NQNN is a primary section from the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. As a synchronous linear motor, it delivers direct linear thrust for positioning stages, gantry axes, and other automation modules where rotary-to-linear conversions are not desired. The A-length primary section pairs with matching secondary tracks in the same series and uses an integrated liquid-cooling circuit for fluid-based thermal management.

This unit sustains a continuous thrust of 550 N while drawing a rated phase current of 4.5 A, allowing stable motion control during long duty cycles. The back electromotive force rises at a rate of 70.2 Vs/m, which indicates the voltage required by the drive at nominal speed. Coil parameters include a winding inductivity of 55.7 mH and a winding resistance of 9.0 Ω measured at 20 °C; together they affect current response and copper losses. Up to 780 W of heat must be removed by the liquid circuit, and the stainless cooling jacket tolerates inlet pressures up to 10 bar. The motor operates at 200 m/min under nominal load, and its 37.5 mm pole width matches the 0150 winding code and the magnetic track geometry. Power enters through 1.0 mm² conductors routed from the front of the housing, and the unit has a standard encapsulation layer for coil protection.

The magnetic circuit generates an inherent attractive force of 2900 N toward the secondary track, so the guideway must absorb that mechanical load. During rapid indexing, the primary section can produce a peak thrust of 2000 N while the drive supplies up to 29.6 A; at that limit, carriage velocity reaches 150 m/min. Thermal equilibrium is regained within 2.4 min after step changes in current because of the short thermal time constant. The motor also has a force constant of 121.70 N/A, does not include an onboard encoder, and uses the standard wire-through-front connection scheme.
