Overview

The Kpower DHV300 is a digital servo motor for positioning tasks in RC models, robotic mechanisms and smart-home linkages. It operates at 6.0–7.4 V and provides 180° ± 3° travel, with listed stall torque of 30.6 ± 0.20 kg·cm at 7.4 V. A brushless motor, aluminum-alloy gears and a 7075 aluminum middle case support a mechanically integrated servo design with a splined output and slotted mounting tabs.

Features

DHV300 digital servo, marked HV DIGITAL and classified as a high-torque model.
Brushless motor with aluminum-alloy gears.
7075 aluminum middle case.
Splined output shaft with a central threaded opening for attaching a suitable linkage or horn.
Mounting tabs with four open-ended mounting slots.
900–2100 μs control signal range, 3 μs dead band and 50–333 Hz refresh frequency.

Applications

RC car steering and aircraft control linkages: the splined output provides a linkage attachment point, while 180° ± 3° travel supports angular positioning within the mechanism’s required range.
Robotic arm and joint linkages: digital positioning and the voltage-specific torque values support selection for mechanisms requiring controlled angular movement.
Smart-home mechanisms: use the servo’s angular travel to position a suitably designed mechanical linkage within the 6.0–7.4 V operating range.
