Product Description:

The MLP200B-0120-FT-N0CN-NQNN linear motor primary section is manufactured by Bosch Rexroth Indramat as part of the MLP Synchronous Linear Motors series. It is installed on the moving carriage of an axis so that magnetic interaction with a passive secondary track produces thrust directly along the stroke, eliminating gearboxes and belts in industrial automation cells. This model uses size 200 with stator length B for compact, high-force linear propulsion.

The unit can deliver a continuous thrust of 3465 N, while its peak attractive force toward the secondary track reaches 15600 N, so the mounting structure must withstand both loads. When short-term overload is required, the motor outputs up to 10900 N of force and may draw 128.6 A from the inverter, while normal process duty is covered by a rated current of 21.8 A. A nominal velocity of 190 m/min is attainable under these conditions, and velocity can still reach 120 m/min at maximum force. A force constant of 159.30 N/A links drive current to linear thrust, and a voltage constant of 91.9 Vs/m indicates the back EMF during motion. Liquid cooling removes 2200 W of power loss, and the required coolant flow is 3.2 L/min through the thermo-encapsulated winding set. Power conductors are routed through the front of the housing with 2.5 mm² cables, and the winding inductance of 12.1 mH together with 2.34 Ω resistance shapes the electrical time response.

The motor weighs 40.0 kg, and its short thermal time constant of 2.4 min means temperature can change quickly under varying load. No encoder is installed, so external position feedback must be provided for closed-loop control. Thermo encapsulation protects the windings from coolant ingress during liquid-cooled operation. The carriage and mounting surfaces must also be rigid enough to handle the magnetic forces generated during service.
