Product Description:

The MLP070B-0150-FS-N0CN-NNNN is a primary segment from Bosch Rexroth Indramat in the MLP Synchronous Linear Motors series. The B-length module with size 070 windings produces direct linear thrust when energized by a compatible drive, replacing ball screws and gear racks in automated transfer lines. By acting directly on the secondary track, it allows precise position control, high repeatability, and reduced mechanical wear in material handling, packaging, and machining systems.

Under continuous duty, the unit develops 820 N of thrust while drawing 7.3 A per phase. The magnetic circuit translates current to force at 111.90 N/A, giving the control system a linear gain for feed-forward force calculations. Back electromotive force rises at 64.6 Vs/m, so the drive must provide adequate voltage headroom as speed increases. Heat created by copper and iron losses is removed through liquid cooling; the internal channel carries coolant past the windings and must dissipate up to 900 W of thermal load. Electrical parameters include 35.0 mH of inductance and 6.1 Ω of resistance, which affect current slew rates and servo loop tuning.

For accelerated moves, the controller may command up to 56.8 A, letting the primary section reach a peak thrust of 2600 N without exceeding its thermal ceiling. Mechanical coupling to the secondary produces an attractive preload of 3750 N, which must be considered when designing guidance bearings and air gaps. A nominal traverse speed of 260 m/min can be sustained, while velocity at maximum force is limited to 150 m/min. To keep temperature stable, the coolant loop must maintain 1.3 L/min and stay at or below the 10.0 bar inlet limit, with only 0.3 bar lost across the plates. The 37.5 mm pole width synchronizes with matched secondary tracks for uniform cogging behavior.
