Product Description:

The MLP070A-0150-FT-N0CN-NQNN is a primary section from the MLP Synchronous Linear Motors series produced by Bosch Rexroth Indramat. As a liquid-cooled linear motor, it mounts to a guided carriage and delivers direct thrust along the track, removing the need for ball screws or belts in automated positioning systems. The assembly follows the 070 size code, length A format, and uses a 37.5 mm pole width to match standard secondary tracks.

The motor supplies a continuous thrust of 550 N, generated with winding code 0150 and a force constant of 121.7 N/A. A rated phase current of 4.5 A can be applied continuously, while up to 29.6 A is available for dynamic peaks. The electromagnetic system produces a back-EMF of 70.2 Vs/m, which sets the drive controller voltage requirement during high-speed motion. Heat created in the copper must be removed, and the integrated liquid circuit requires 1.1 l/min of coolant; the channel is formed through a thermo-encapsulation method that seals the coils. With winding inductance of 47.9 mH and resistance of 9.0 Ω at 20 °C, the mover presents a predictable load to the inverter. Power conductors of 1.0 mm² exit at the front of the housing, simplifying cable routing, and the thermal time constant of 2.4 min indicates rapid temperature rise if coolant flow is interrupted.

An attractive magnetic preload of 2900 N keeps the mover seated on the reaction plate, while controllable thrust reaches 2000 N for fast acceleration phases. During heavy loading, the unit may be limited to 150 m/min. Under nominal conditions, it can run at 200 m/min without exceeding the winding temperature class. Up to 780 W of loss power must be carried away by the coolant loop. No encoder is installed, so position feedback must be provided by an external scale or resolver integrated elsewhere in the axis.
