Key Features

• Ø7mm coreless planetary gearmotor for compact cosmetic actuator modules: coreless brushed DC motor integrated with a plastic planetary reduction stage to fit tight envelopes while maintaining controllable output speed/torque for small applicator mechanisms.
• Cross output interface for molded plastic couplers: form-fit drive profile intended for small levers/cams/couplers used in cosmetic applicators; reduces reliance on set screws when assembly space is limited. Alternative shaft styles can be reviewed based on your mating-part drawing.
• Motor length options to match packaging and duty cycle: 10mm / 14mm / 16mm / 20mm motor body lengths available; production configuration supported for lead length, connector/terminal, polarity marking, and wire exit direction.

Cosmetic Applicator / Brush-Head Actuator Use Case

Cosmetic applicator mechanisms typically drive a small brush head or applicator element through a compact plastic transmission path (lever, cam, micro gear, or coupler). This Ø7mm coreless planetary gearmotor is suitable for these designs where the priority is stable output in a limited envelope, frequent start/stop operation, and strict constraints on mass and perceived noise.

The plastic planetary stage supports compact reduction in a lightweight package. The cross output interface is intended for direct mating with molded couplers commonly used in brush-head and applicator assemblies, improving torque transfer consistency when there is limited space for clamping or set screws. If your mechanism includes end-stops, current limiting is recommended to avoid extended operation near stall conditions.

Cross Output Interface & Plastic Housing (Engineering Notes)

This motor uses a cross-type output to provide a form-fit interface in very small assemblies. Compared with a smooth round shaft, the cross profile improves coupling stability when the mating part is molded plastic and the design cannot accommodate set screws.

A protective plastic housing is used around the gearbox section to protect the geartrain during handling and assembly, and to simplify installation into compact modules. For applications with high duty cycle, shock loading, or repeated hard end-stops, please confirm your duty cycle and target output torque so we can recommend an operating point with adequate margin.

Selection Notes (Motor Length & Working Point)

Motor body length options 10mm / 14mm / 16mm / 20mm allow you to balance axial space with torque reserve and thermal margin. Shorter lengths may be sufficient for light-load intermittent motion. Longer lengths are typically selected to improve operating stability under higher duty cycle or higher load.

To shorten sampling time, please provide: target output speed (rpm), required torque (or force at a known lever radius), supply voltage range, duty cycle (on/off timing), and end-stop behavior. We will propose a configuration and test point suitable for sampling and production.

Reference values are based on sample builds. Final performance should be confirmed with your load profile, duty cycle, and end-stop condition.

Integration & Customization Options

For production builds, the motor can be configured with:

Lead wire length / wire gauge / polarity marking
Connector or terminal type (per your harness standard)
Wire exit direction for your assembly process
Alternative output shaft style (round/D-shaft/threaded/press-fit pinion; drawing review required)
Speed/torque targeting via winding & gearbox ratio selection

FAQs

Q1: Is this motor suitable for cosmetic applicator or brush-head actuator mechanisms?

Yes. This Ø7mm coreless planetary gearmotor is intended for compact personal care actuators such as cosmetic applicators and small brush-head drives. To confirm suitability, we match the configuration to your target rpm, required torque, voltage range, and duty cycle—especially if the mechanism has end-stops.

Q2: What is the cross output used for, and can you change the output style?

The cross output is designed for form-fit coupling with molded plastic couplers/levers/gears in very small modules, improving torque transfer consistency compared with a smooth round shaft in the same envelope. If you need round shaft, D-shaft, threaded shaft, or a press-fit pinion, please provide your mating-part drawing and tolerance requirements for review.

Q3: What information should we provide to get the correct quotation and samples?

Please share: target output speed (rpm), target output torque (or force at a known radius), supply voltage range, duty cycle (on/off timing), and whether the mechanism has hard end-stops. If you also provide wiring/connector requirements and the mating-part drawing for the output interface, we can align the sample build to your assembly process and incoming inspection checks.
