Product Description:

The MLP200A-0090-FT-N0CN-TQNN is a linear motor primary section produced by Bosch Rexroth Indramat within the MLP Synchronous Linear Motors series. It relies on liquid cooling, and the coolant conduits plus power leads are routed through the front face to simplify cabinet integration. The design matches motor size 200 with length code A, offering a compact active segment that fits standard secondary tracks. Because no encoder is installed, the drive system must use an external position sensor to close the position loop.

Electromagnetic output begins with a force constant of 186.70 N/A, so each ampere of phase current produces that amount of linear thrust. Under steady thermal conditions, the coil produces a continuous nominal force of 2415 N, while dynamic moves can reach a maximum force of 7450 N before the control limits intervene. These values are supported by a rated current of 12.9 A and an allowable peak of 69.6 A. The voltage constant is 107.8 Vs/m, giving the drive the back-EMF scaling needed for controller matching. Winding code 0090 corresponds to the electrical geometry and results in an inductance of 22.7 mH and a phase resistance of 4.5 Ω at 20 °C, which influence current-loop bandwidth.

Mechanical and thermal limits include an attractive force of 10700 N acting between the primary and the permanent-magnet track, which is important for bearing selection. At the nominal feed rate of 170 m/min, the motor dissipates 1700 W of power loss, so a coolant flow of 2.4 L/min is required. The circuit may be pressurized up to 10.0 bar without leakage risk. A pole width of 37.5 mm sets the commutation pitch, and the maximum attainable speed at full thrust is 90 m/min. The 28.3 kg mass and the thermo-encapsulation method provide structural stiffness and protect the windings from moisture.
