عرض التفاصيل الكاملة

Overview

The Kpower DM0090 is a compact PWM servo motor for positioning small robotic linkages. It combines metal gears with a plastic case and operates from 4.8 to 6.0 V. Its specified travel is 120° ± 15°, with voltage-dependent speed and stall torque. The 22.4 × 12.5 × 22.8 mm body helps buyers assess installation space for their mechanism.

Features

Metal gears and a plastic case.
PWM control with a 900–2100 μs pulse-width range and 5 μs dead band.
120° ± 15° travel for limited-angle positioning.
4.8–6.0 V operation, with separate performance specifications at each endpoint.

Applications

Use the DM0090 to position a small robotic-arm linkage or move a compact robot mechanism through a limited angle. PWM control provides the positioning interface, while the compact body supports installations with restricted space. Account for the 120° ± 15° travel and the voltage-specific speed and stall-torque values when designing the mechanism.
