g500 + MCS/MCA/m850 servo geared motors 0.25–20.3 kW

Country: Germany · Model: g500 + MCS/MCA/m850

Servo geared motors based on the g500 combine a helical, shaft-mounted or bevel gearbox with a synchronous or asynchronous servo motor. Power is 0.25–20.3 kW, output torque 3–4500 N·m. For dynamic drives that need accurate positioning.

Description

Servo motors come in three types. The MCS are synchronous and highly dynamic, 0.25–15.8 kW; the m850 are synchronous and compact for medium dynamics, 2–9.2 kW; and the MCA are asynchronous with a low moment of inertia, 0.8–20.3 kW. Feedback is provided by resolvers or OCT single-cable encoders. The g500 gearboxes have high permissible radial loads, low backlash and closely spaced gear ratios, and come in two-, three- and four-stage versions. The bevel g500-B is compact and gives an angular layout, the g500-S is a narrow shaft-mounted unit, and the g500-H is a sturdy axial one. All combinations are matched with i700, i750 and i950 cabinet servo inverters. As an assembly the unit is classified as a motor under code 8501.

How to choose

First choose the motor by dynamics, then the gearbox by torque. With the MCS the output torque of the g500-B is 6–4300 N·m (up to i=2935), the g500-S 8–4500 N·m (up to i=4640), the g500-H 3–3000 N·m (up to i=3240). With the m850 the ranges are 22–4300, 17–4500 and 15–3000 N·m. With the MCA they are 10–4300, 10–4500 and 9–3000 N·m. For torques up to 20 000 N·m and motors up to 55 kW there is the separate g500-B.
