Inrunners vs Outrunners

Most engineers choose based on torque, that is the wrong starting point

Torque is not the limiting factor.
Cooling is:
- Heat is generated in the coils
- Must reach the mounting surface
- Thermal resistance defines performance

Inrunner best suited for high dynamic performance, and compact, integrated designs such as:
- Semiconductor systems
- Precision positioning stages
- High-speed indexing
- Spindles
- Robotics with fast response

Outrunner is best suited for high torque at low speed. In high inertia systems such as:
- Conveyor rollers
- Belt drives
- Drums
- Large diameter rotary tables

When is a standard motor not enough?

That's where customization starts

Usually when your application requires custom voltages, integrated cooling, different cables, vacuum or cleanroom compatibility, higher force density, or lower force ripple. Or simply dimensions that don't exist in a catalog. At Tecnotion, customization ranges from adapted cables and optimized windings to completely tailor-made direct drive motors developed by a multidis...

Coupling of linear motors

Does your machine need a performance upgrade?

Coupling linear motors is a practical way to increase available force and system performance while maintaining the existing machine architecture. Total force: In a coupled configuration, the total force generated by the system equals the sum of the forces produced by the individual motors. Load distribution: Using multiple motors allows force to be distributed across l...
