Product Description:

The MLP100A-0150-FT-N0CN-NNNN linear motor primary section is produced by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. It uses motor length code A and motor size 100, giving a compact footprint suited to lightweight carriages that need direct electromagnetic thrust rather than ball-screw translation. In automated pick-and-place axes, gantry stages, or machining centers, the part converts drive current into linear motion along a 37.5 mm pole track without intermediate mechanics.

During continuous duty, the motor develops 1180 N of thrust while drawing a rated phase current of 9.2 A. This output corresponds to a force constant of 127.80 N/A, so each ampere produces a fixed increment of force. The back-EMF characteristic uses a voltage constant of 73.8 Vs/m, which determines inverter voltage demand at speed. Travel velocity in normal operation reaches 220 m/min. Winding set 0150 has an inductance of 27.3 mH and a resistance of 4.9 Ω at 20 °C. Liquid cooling circulates through 0.114 l of internal duct volume, and a flow rate of 2.0 l/min with a 2.4 min thermal time constant keeps the stator within limits. The coils are protected by a thermo-encapsulation method, and the assembly mass is 17.0 kg. Power conductors exit at the front of the housing, and no encoder is installed at the factory.

For short strokes or acceleration peaks, the drive can supply 3750 N of force by allowing up to 50.8 A of phase current. Magnetic preload toward the iron secondary track equals 5400 N and must be countered by linear bearings. When the motor is loaded to its maximum force, traverse speed is limited to 150 m/min to stay within thermal and voltage limits. The liquid-cooled construction supports repeated overload cycles without sustained temperature rise. The lack of an internal encoder allows the user to add external position feedback or operate sensorless, depending on the control method.
