RobStride 05 QDD 5.5N·m Integrated Robotic Actuator Module – 7.75:1 Ratio, 48V, Dual Magnetic Encoders, 191g, FOC Control

Product Description

The RobStride 05 QDD 5.5N·m Integrated Actuator Module is a compact, high-performance solution combining motor, planetary reducer, and driver into a single unit. Delivering a peak torque of 5.5 N·m with a lightweight 191g build, it is ideal for robotics, automation, and smart mobility applications. Featuring a 7.75:1 reduction ratio, dual 14-bit magnetic encoders, and FOC (Field-Oriented Control), it ensures precision, efficiency, and responsive motion control. Its wide 15–60V voltage range, Class B insulation, and robust design support operation in diverse environments from -20°C to 50°C.

Key Features

• Integrated Design – Motor, reducer, and driver in one compact 46×46×44 mm unit.

• High Performance – Peak torque of 5.5 N·m, rated torque of 1.6 N·m at 100 rpm, with 0.94 N·m/Arms torque constant.

• Dual Magnetic Encoders – Two 14-bit absolute encoders for precise position feedback.

• FOC Drive Control – Smooth, efficient torque output with closed-loop temperature control algorithms.

• Versatile Power Range – Operates from 15–60V, optimized for 48V systems.

• Lightweight & Durable – Only 191g ±10g, 20-pole motor, and Class B insulation for reliable operation.

Applications
