why engineers specify maxon
Precise motion packages without uncontrolled sourcing risk
Gearhead matching
Planetary stages are paired by torque, bearing load and duty cycle, with ratios documented for thermal rise and acoustic limits.
Controller continuity
EPOS and ESCON drive data keeps current loops, encoder feedback and safety limits aligned from prototype to serial production.
Regulated documentation
ISO 13485, AS9100 and CE files support purchasing teams that need traceability, change notification and controlled component evidence.

Specification answers before RFQ
Which maxon DC motor family fits low inertia positioning?
DCX ironless rotor motors are commonly reviewed first when the axis needs fast acceleration, smooth low speed behavior and compact diameter below 35 mm.
Can EC motors ship as motor, gearhead and controller sets?
Yes. The engineering review can combine EC-i or EC-flat motors with GPX gearheads, encoders and EPOS positioning controllers as one validated motion stack.
What documents are available for regulated devices?
Datasheets, production certificates, change notes and quality system evidence can be aligned with ISO 13485, AS9100 and CE machinery directive requirements.
Send the duty cycle, envelope and certification target.
Our specification team will return a motor, gearhead and controller path with torque margin, thermal assumptions and document requirements clearly marked.
