Product Description:

The MLP052A-0300-FT-N0CN-NNNN is a primary section from the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. This flat, coil-based component produces direct linear thrust when paired with a toothed secondary track, eliminating gearboxes or ball screws in automation axes. By converting drive current directly into push-pull motion, it supports fast, precise positioning for pick-and-place gantries, packaging stations, and high-speed transport lines where compact form and high duty cycles are required.

During continuous duty, the actuator supplies 300 N of thrust and can deliver a peak of 650 N for short acceleration bursts. The magnetic circuit uses a 30.0 mm pole width, allowing a nominal carriage speed of 350 m/min and 300 m/min when loaded to maximum force. A force constant of 60.0 N/A links current to thrust, and the winding has an RMS current rating of 5.0 A while tolerating surges up to 13.8 A. Generated copper losses reach 300 W, so liquid cooling channels remove heat at 1.0 l/min to stabilize temperature. Power leads and thermal hoses exit the front of the housing, while the thermo-encapsulation method holds the winding pack against vibration. The primary segment weighs 5.0 kg, carries the 052 frame designation, and is supplied without an encoder, so external feedback must be provided.

Performance is aided by the short 3.7 min thermal time constant, allowing the motor to accommodate frequent duty-cycle changes before reaching equilibrium. Installation designers must account for an attractive preload of 1300 N between the primary and the magnetic rail. Electrical behavior includes a 37.6 Vs/m voltage constant, a 56.0 mH phase inductance, and a 5.0 ohms phase resistance. The 0300 winding code and A length indicate the coil geometry, keeping the module compact while meeting the velocity capability required for this motor size.
