Lenze g350-P Precision Planetary Geared Motors
The Lenze g350-P Series (featured model: g350-P90/m550-P80M4 0.75 kW IE3) represents Lenze's high-precision planetary gearbox platform, engineered specifically for high dynamic servo applications, high-frequency start-stop cycles, and precision indexing motion. Achieving low torsional backlash ($\le 3\text{ to } 8\text{ arcmin}$) and high torsional stiffness, g350-P planetary gearboxes cover output torque capacities from 25 Nm to 320 Nm across 6 standard frame sizes (P50 to P320). Matched with modern **Lenze MCA Synchronous Servo Motors**, **Lenze m550 IE3 Premium AC Motors**, or the revolutionary **Lenze Smart Motor**, g350-P planetary geared motors provide 100% direct 1-to-1 mechanical compatibility to replace legacy **Lenze MPR / MPG Series** planetary reducers across packaging robotics, CNC axis drives, pick-and-place systems, and printing machinery.

Expert Selection & Retrofit Engineering Notes
When replacing older Lenze MPR / MPG Series planetary gearboxes or competing Neugart PLN / Alpha LP servo planetaries, switching to current g350-P series models guarantees 100% exact physical mounting alignment without re-programming PLC motion parameters. Simply supply us with your existing Lenze nameplate serial number or code (e.g., g350-P90-m550-P80M4), and our technical team will deliver a 100% compliant replacement specification and proposal.
