Dimension Drawing
Engineering Value for Product Development
Ultra-compact planetary transmission
The 6 mm-class package fits miniature mechanisms where conventional gear motors cannot. The planetary structure concentrates reduction in a compact coaxial layout.
Low-speed output from a miniature motor
The 110:1 reference ratio reduces the motor speed to a 550 ±10% RPM no-load gearbox output, suitable for compact actuators requiring controlled motion rather than direct high-speed rotation.
Fast start-up and low-voltage actuation
A specified starting voltage below 1.5 V supports responsive start-up. Loaded start behavior must still be validated at the minimum system voltage and worst-case resistance.
Current margin for compact electronics
The source provides 60 mA maximum no-load current and 400 mA stalling current. Driver, battery and protection design should be based on the real start/load waveform, not no-load current alone.
Main Applications
Smart Agriculture & Gardening
Miniature sensor adjustment, lightweight valve actuation, compact dosing/seed-control mechanisms and small precision actuators.
Focus: Validate system-level dust/moisture protection, start-up resistance, vibration, temperature and duty cycle.
Automotive Electronics
Small precision adjustment, optical/sensor actuation, compact cabin mechanisms and other low-load micro actuators requiring a coaxial package.
Focus: Automotive use requires project-specific temperature, vibration, durability and qualification testing beyond the base specification.
Smart Home
Compact locks, shutters, blinds, personal-care devices, micro valves and miniature opening/closing mechanisms.
Focus: Balance speed, stall margin, current draw, noise, output-interface fit and cycle life in the actual product.
Medical Equipment
Portable diagnostic devices, micro pumps/valves, handheld instruments and compact motion modules where small size and low noise matter.
Focus: Medical suitability depends on device risk level and customer validation; verify noise, temperature rise, life and consistency.
AI Robots
Micro grippers, sensor modules, small joints, head/eye mechanisms and other light-load precision actuators.
Focus: Evaluate backlash, output-interface stiffness, reversing impact, stall risk and repeated start-stop cycles.
Industrial Automation
Optical adjustment, micro dosing, small inspection tools, miniature fixtures and low-load positioning mechanisms.
Focus: Separate continuous, starting and peak torque requirements and validate the real cycle profile.
Commercial / Office Equipment
Card/receipt handling, miniature shutters, lock modules, compact dispensing and small opening/closing mechanisms.
Focus: Evaluate jam conditions, noise, cycle life and recovery logic instead of simply oversizing the motor.
Custom Micro-Drive Applications
Non-standard mechanisms where the 6 mm package or output interface must be adapted to a customer structure.
Focus: Provide mechanism drawing, voltage, target speed, load profile, duty cycle and annual demand for evaluation.
Customization Range
Output Installation Interface
The source specification explicitly states that the output installation position, size and style can be customized according to customer requirements.
Lead Wire
The reference drawing shows 40 ±2 mm lead wires and marks the wire length as customizable. Connector/terminal requirements should be supplied by drawing or sample.
Performance Matching
Voltage, target output speed, load profile and duty cycle can be evaluated around the customer mechanism. Final rated load/current/speed must be confirmed through an approved project specification.
Noise & Reliability
Project validation can cover noise, temperature, start-stop cycles, reversing, stall events and interface durability according to the customer's actual test conditions.
Feedback / Control Options
If position or speed feedback is required, feasibility should be evaluated against the available installation space and control architecture.
FAQ
Q1. What applications are best suited to the Coreless Gear Motor?
The Coreless Gear Motor is best suited to miniature mechanisms where installation space is extremely limited and compact coaxial reduction is needed. Typical use cases include micro grippers, sensor adjustment, compact lock/valve modules, precision instruments and other light-load actuators.
Q2. What are the confirmed electrical parameters for the reference model?
For SLM-P0609-110-DZ, the source confirms DC 6 V rated voltage, 60 mA maximum no-load current, 550 ±10% RPM no-load speed, 400 mA stalling current, 200 gf·cm (0.2 kgf·cm) stalling torque, starting voltage below 1.5 V, operating noise below 50 dB(A), -20 to 65 °C operating temperature and 110:1 gear ratio.
Q3. What are the rated load, rated current and rated speed?
The source specification marks all three items as TBD. They should be determined and frozen during project validation; this page does not estimate them.
Q4. How should stall risk be handled in the final product?
Use current limiting or current detection, action timeout, position/end-stop logic and appropriate mechanical protection. The 400 mA stalling current is a protection reference, not a recommended continuous operating point.
