Product Description:

The MLP300C-0060-FS-N0CN-NNNN is a primary section from the MLP Synchronous Linear Motors series manufactured by Bosch Rexroth Indramat. As a direct-drive actuator, it eliminates gearboxes and screws by generating thrust along its 37.5 mm pole pitch. The unit belongs to motor size 300 and is supplied with a standard encapsulation method that shields the winding package. Wire routing is through the front of the housing, and no encoder is installed, so position feedback must be provided externally when the motor is integrated into automated pick-and-place stages, portal axes, or transfer shuttles.

The electromagnetic section delivers a continuous force of 6,720 N at the rated current of 29.6 A. Short-duty peaks can reach 21,500 N while drawing up to 143.1 A, allowing rapid acceleration of medium-mass payloads. These values are associated with winding code 0060, an inductance of 11.4 mH, and a resistance of 2.4 Ω measured at 20 °C. A maximum velocity of 60 m/min is available when the mover is loaded to its peak force. The winding set is cooled by a liquid circuit that must accept 4.6 l/min of flow, and this requirement helps keep copper temperature within safe margins and prevent demagnetization. Power conductors use a 4.0 mm² cross-section to minimize voltage drop along the stator leads.

With a voltage constant of 130.9 Vs/m and a force constant of 226.90 N/A, drive controllers can predict back-EMF and size current loops accurately. The magnetic attraction toward the secondary track reaches 30,700 N, a value that must be countered by mechanical restraints during installation. Under nominal excitation, the stage travels at 110 m/min, and the motor has a thermal time constant of 2.4 min. Maintaining the specified coolant flow yields a pressure loss of 2.8 bar across the internal channels, ensuring that the liquid cooling circuit removes waste heat as the motor approaches its electrical limits.
