Product Description:

The MLP300C-0060-FT-N0CN-NNL3 is a primary section from the MLP Synchronous Linear Motors series produced by Bosch Rexroth Indramat. As a liquid-cooled synchronous linear motor, it delivers direct thrust along a track without mechanical transmissions, making it suitable for high-speed pick-and-place axes, gantry stages, and machining centers that demand precise linear positioning. The design supports direct linear motion, so the drive system can move the carriage without gears, belts, or screw mechanisms in the force path.

This model produces a continuous nominal thrust of 6720 N while drawing a rated phase current of 29.6 A. Its force constant is 226.9 N/Amp, which indicates how much linear force the motor generates for each ampere supplied by the drive amplifier. Under rated conditions, the carriage can travel at a nominal velocity of 110 m/min, and the copper and iron losses removed by the cooling circuit amount to 3200 W. Heat is extracted through an internal channel fed by 4.6 L/min of coolant, and the inlet line may be pressurized up to 10 bar. The thermo-encapsulation method seals the windings, and power leads are routed through the front of the module to simplify cable routing inside the machine frame.

For short duty cycles, the motor can reach a peak thrust of 21500 N, and at that force the carriage attains a top speed of 60 m/min. A static attractive force of 30700 N must be considered when sizing air gaps and guide bearings. The laminated stator stack uses a 37.5 mm pole width that corresponds to winding code 0060, resulting in a winding inductance of 11.4 mH and a DC resistance of 2.4 Ω at 20 °C. Because no encoder is installed, external position feedback must be provided by the machine controller. Pressure drop across the cooling channel is 2.8 bar, and the voltage constant is 130.9 Vs/m for drive matching.
