Product overview
The Kpower MB0090 is a miniature servo actuator for applications including fixed-wing drones, RC model aircraft and medical equipment. Its physical architecture combines a plastic housing, metal gearing, a brushed DC motor, a potentiometer position sensor and a 1BB bearing specification. The body measures 22.8 × 12.4 × 28.3 mm, defining the space needed for integration. Although marketed with a 9G designation, its specified weight is 13 g, which is the relevant figure for component mass budgeting.
The MB0090 accepts PWM control and operates across 3.7–6 V. At 6.0 V, its specified stall torque is 3 kg·cm, no-load speed is 0.08 seconds per 60°, and stall current is 1000 mA. Travel is 180°, with customization supported for travel, protocol and ingress protection. Operating temperature is limited to −10 to 50°C, and the listed protection rating is IP42. Output coupling details conflict: the dimensional spline specification is 20T, Φ4.76 mm, while another feature identifies a 25T spline.
