Product Description:

The MLP140B-0090-FT-N0CN-N305 is a primary section of a synchronous linear motor produced by Bosch Rexroth Indramat in the MLP Synchronous Linear Motors series. Intended for gantries, pick-and-place modules, and other positioning axes, the unit replaces rotary motion with direct linear thrust so mechanical transmissions are unnecessary. In an automation line, it generates controlled push-pull force along a magnetic track, allowing high acceleration, repeatable positioning, and low maintenance compared with ball-screw or belt drives.

At its continuous operating point, the mover delivers 2415 N while drawing a rated phase current of 14.0 A. That steady output is governed by a force constant of 172.80 N/A, so each ampere supplied through the three-phase winding directly scales the generated thrust. The coil set uses a 140 frame width with length code B and winding code 0090. Under rated excitation, it reaches a nominal carriage speed of 160 m/min, supported by a voltage constant of 99.7 Vs/m that corresponds to the back EMF seen by the drive. The winding resistance is 2.6 Ω and the inductance is 14.2 mH, which shape current-loop dynamics and inverter sizing.

When the application demands short bursts, the mover withstands a peak force of 7650 N and a corresponding peak current of 79.3 A, while the magnetic attraction to the secondary track reaches 11000 N. Heat produced during such peaks equals 2512 W of power loss, so the assembly uses liquid cooling. A flow of 3.6 L/min through the internal channel limits temperature rise with only 0.9 bar of pressure loss. Thermo-encapsulation secures the windings and contributes to a mover mass of 30.1 kg. Maximum traverse under full load is 90 m/min, and Hall-less operation is used because no encoder is installed. Power and sensor leads exit from the front of the housing to simplify cable routing.
