Product Description:

The MLP100A-0090-FT-N0CN-NQNN primary section is manufactured by Bosch Rexroth Indramat for the MLP Synchronous Linear Motors series. It converts drive current directly into linear thrust for axes that cannot use rotary transmissions. Because the unit is built without an encoder, the machine must provide external position feedback for closed-loop motion control. As a primary section, it is the energized mover element rather than the passive rail. Size 100 and length code A indicate the active cross-section and coil pack length, which match the standard secondary track used by this motor family. This arrangement suits fast transfer systems that need direct linear motion with minimal transmission compliance.

The winding code 0090 yields a continuous thrust of 1180 N at a rated phase current of 5.9 A. Force rises in proportion to current according to a motor constant of 198.90 N/A, while motion generates back EMF in line with a voltage constant of 114.80 Vs/m. Heat from copper and iron losses is removed by liquid cooling, and a flow rate of 2.0 l/min can pass through the integral jacket at inlet pressures up to 10 bar. Electrical connections enter through the front of the housing, which can help when side clearance is limited. The three-phase winding has 66.9 mH of inductance and 12.0 Ω of resistance for drive tuning. Pole width is 37.5 mm. Under rated load, nominal velocity reaches 150 m/min, while peak demand can draw 34.2 A and reduces speed to 90 m/min.

Peak thrust capability is 3750 N, and the passive magnetic circuit exerts an attractive force of 5400 N toward the secondary. Guide bearings therefore need enough capacity to carry the magnetic preload during operation. Under continuous duty, the assembly dissipates 1500 W into the coolant loop, and thermo-encapsulation helps stabilize the coil structure against vibration and moisture. The mover mass is 17.0 kg, which supports use on gantry, pick-and-place, and transfer-line axes that benefit from direct linear actuation.
