Product Description:

The MLP140A-0120-FT-N0CN-NNNN is a synchronous linear motor module produced by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. As a thrust-producing primary section, it mounts on the moving carriage and interacts with a stationary secondary track to translate electrical energy into linear motion for gantries, pick-and-place axes, and high-speed transport systems used in industrial automation. This arrangement lets the moving member generate force directly along the axis without a rotary-to-linear transmission stage. Its role is to provide the powered section of the axis while the secondary track remains stationary. No encoder is installed, so position feedback must be supplied by an external scale.

The unit’s continuous nominal thrust capacity is 1680 N, allowing long-term operation without thermal derating when the windings are supplied from a link voltage of 540 V DC. For rapid acceleration, the motor can deliver up to 5200 N of peak force, subject to drive current limits and magnetic saturation. A rated phase current of 12 A produces the nominal force, while integrated liquid cooling channels circulate coolant through the stator laminations to remove heat efficiently. The active section uses a laminated magnetic core to concentrate flux, and the A length code pairs with a 140 mm width to fit compact machinery where installation space is limited. Cabling exits at the front of the housing, which can simplify routing along the carriage in linear axes with narrow side clearance. The coils are sealed by a thermo-encapsulation method that protects them against vibration and moisture during repeated motion.

The moving section has an enclosure rating of IP65, so it resists dust ingress and low-pressure water jets along the travel path. Dynamic events that exceed the rated region are handled by a drive current ceiling of 70 A, enabling short bursts of extra thrust without overheating the windings. During routine positioning tasks, the carriage can reach a nominal speed of 190 m/min, while the maximum velocity at full force is 120 m/min. The laminated iron core supports the magnetic circuit and contributes to the pull forces present during operation.
