Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Beckhoff Automation 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.
Low-voltage brushless DC servo motors for 48 or 96 VDC systems, with a 12-slot/10-pole design, matched to the Kinco FD1X5 drive and aimed at robotics, CNC and automated lines.
| Published maximum | AM8100 | SMK Series Low-Voltage DC Servo Motors |
|---|---|---|
| Power | 750 W | 5,000 W meets or exceeds |
Low-voltage (24-48 VDC) brushless servo motors with a 12-slot/10-pole low-cogging design, IP65 and a choice of optical or magnetic, incremental or absolute encoders. Matched to Kinco FD1 and OD drives for battery-powered and mobile machines.
| Published maximum | AM8100 | SMC Series Low-Voltage DC Servo Motors |

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.
