High power density
thanks to high overload capacity, high torsional stiffness and pull-out rigidity, as well as mechanical clearance
thanks to very high positioning accuracy and its quick response time
through modular design integration, which allows countless combination possibilities.
Extreme precision under high acceleration torques – those are the outstanding features of ZN.. series cycloidal servo gearmotors. Their performance data makes them unique – whether you emphasize torque, stiffness or weight.
The gearmotor is shipped with lubrication for life, ready for installation and available in twelve sizes. We especially emphasize the features of the cycloidal servo gearmotor: It excels by mechanical clearance and its high torsional stiffness and pull-out rigidity as well as excellent overload capacity. This allows even demanding tasks such as exact positioning or fast movement of heavy loads to be performed with a high degree of repetitive accuracy.
The gear unit is made up of a CMP../CM.. motor, an intermediate flange and a two-stage cycloidal gear unit. Gear unit and motor can be combined in many ways using the SEW-EURODRIVE modular system.
Furthermore, our ZN.. cycloidal servo gearmotors’ compact design ensures optimum mounting options and application possibilities – even in confined installation spaces. Our ZN.. series of cycloidal servo gearmotors combine power density and dynamics, maximum performance, and precision.
Naturally, the ZN.. servo gearmotors are optimized for use with the MOVIDRIVE® B application inverter and the MOVIAXIS® multi-axis servo inverter in combination with the MOVI-PLC® controller.
