Product Description:

The MLP100A-0120-FS-N0CN-NQNN is a primary section in the MLP Synchronous Linear Motors series produced by Bosch Rexroth Indramat. It is designed to generate linear thrust without mechanical conversion, forming the active part of a linear axis when paired with a passive secondary track. By energizing its windings with three-phase current, the unit travels along the track and positions tooling heads or gantry bridges in factory automation systems that demand high speed and repeatable force.

Tuned for continuous duty, the motor delivers a continuous nominal force of 1180 N. During acceleration, it reaches a maximum force of 3750 N, limited by magnetic saturation and current capacity. A rated current of 7.4 A sustains nominal thrust, while temporary peaks up to 40.5 A are tolerated. The force constant of 160.40 N/A indicates the proportional relation between current and output force. A winding inductivity of 43.8 mH affects current rise time and commutation behavior. A copper resistance of 7.9 Ω at 20 °C contributes to I²R losses and continuous heat generation. The primary exerts 5400 N of attractive pull toward the secondary, so rigid guides are required. With a voltage constant of 92.5 Vs/m, back EMF stays within inverter limits at the 190 m/min nominal velocity. Standard encapsulation protects the windings, and the power leads are routed through the front of the housing.

Heat is removed by liquid cooling, and the internal channels accept a coolant flow of 2.0 l/min with a max inlet pressure of 10.0 bar. This circuit dissipates the declared power loss of 1500 W, enabling a thermal time constant of 2.4 min and helping keep copper temperature stable when the axis runs at 120 m/min under full load. Motor size 100 with length code A provides a compact footprint for gantry carriages, and the absence of an encoder allows integration of an external feedback element suited to the control topology.
