- Seamless integration – Optimized for mobile applications
Servo-Kit ILM-E85x23
How TQ Motors Enhanced upstair’s Prototype
The first upstair prototype used outrunner motors, which lacked the necessary form factor and technical specifications. By switching to ILM-E85x13 and ILM-E85x23 motors, upstair reduced weight, improved compactness, and ensured full sealing. Additionally, TQ’s German-based support provides direct assistance for technical questions, a major advantage for the upstair team.
Climbing and Driving – Two Motors, One Perfect Solution
- ILM-E85x13 – Paired with a gearbox and servo brake, this motor powers the stair-climbing mechanism.
- ILM-E85x23 – Provides increased performance, enabling the system to handle inclines up to 20 percent and ensuring smooth mobility.
