The new precision servo gearmotors of the ZN.. series offer you a dynamic and highly flexible drive solution with overload capacity. Ideal for demanding applications such as gantry, rotary table or tie sheet inserter. Because these applications demand top performances in terms of torque, stiffness and precision.
ZN.. series servo gearmotors – compact, precise, powerful
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.. servo gearmotors' compact design ensures optimum mounting options and application possibilities – even in confined installation spaces. This way, they combine our ZN.. series servo gearmotors. Power density, precision and dynamics.
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.
