Electric Motors
RLS is strongly rooted in motor drive technology and has been developing encoder solutions for speed and position control for decades.
Key features
Commutation support
UVW signals and absolute position on power-up enable immediate field-oriented control without homing.
High speeds
Qualified for operation at speeds up to 100,000 rpm in high-speed spindle and servo applications.
Why RLS
Challenges
- High electrical noise from motor windings and switching inverters
- Thermal cycling from motor heating and cooling
- Integration inside the motor housing with minimal axial space
Our solutions
- Differential signal outputs (ABZ, UVW) reject common-mode EMI
- Operating temperature from -40 °C to +125 °C matches motor thermal profiles
- PCB-level ICs integrate directly inside the motor end cap
