Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a WITTENSTEIN alpha 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.
Leadshine motor-plus-drive units from 200 to 750 W on 24-48 VDC, with 17-bit magnetic encoders, CANopen or Modbus/pulse control and up to 300% overload, published in the Leadshine low-voltage DC catalogue.

Kinco's latest integrated low-voltage servo motor with the drive built in, offered in 40, 60 and 80 mm frames from 100 to 750 W. It carries CANopen, Modbus RTU or EtherCAT, IP65 as standard (IP67 optional) and an optional gear reducer.
View series →First-generation Kinco integrated servo motors for intelligent logistics: 200-750 W, 3000 rpm, with 16-bit absolute feedback and a choice of pulse, CANopen, EtherCAT or Profinet control.
View series →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.
