Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a maxon part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 3 series from our supply network are the closest match on published figures.
Kinco integrated servo motors at 400 W to 1 kW in 60 and 80 mm flanges with optional STO, optional brake, IP20 or IP65 housings and Modbus, CANopen, EtherCAT or Profinet interfaces.

Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
