Product Description:

The MLP070B-0250-FS-N0CN-NNNN is a primary section from the MLP Synchronous Linear Motors series produced by Bosch Rexroth Indramat. With motor size 070 and length code B, this liquid-cooled unit provides direct thrust for pick-and-place axes, gantry stages, and other automation zones where rotary-to-linear conversions are undesirable. By embedding windings in a standard encapsulation method and routing its power leads through the front face, the part delivers contact-free force along a mating secondary track and eliminates mechanical transmissions.

In continuous operation, the motor delivers 820 N as its continuous nominal force when coolant holds the windings at rated temperature. For short acceleration bursts, it reaches 2600 N, and a magnetic attractive load of 3750 N must be considered in the mechanical guides. The relation between phase current and thrust is given by a constant of 79.10 N/A. During nominal duty, the windings draw 10.4 A, and the back EMF increases at 45.6 Vs/m. Liquid cooling removes heat through a circuit that requires 1.3 l/min of flow and accepts inlet pressure up to 10 bar. The standard encapsulation resists condensation, and power is supplied through 1.0 mm² leads routed at the front.

The dynamic profile suits axes that move quickly. The slider attains 250 m/min at maximum thrust and maintains 400 m/min under continuous load. Transient moves draw up to 57.1 A, so drive sizing must account for the 17.0 mH inductance and 3.0 Ω resistance of winding code 0250. Heat under those peaks is measured as 900 W, which the liquid circuit must remove. The 10.4 kg mass adds thermal inertia, and the unit ships without an encoder, leaving position feedback to external scales. Its standard encapsulation preserves insulation, and length code B fits compact 070 size assemblies.
