10mm Geared Stepper Motor Dimensions and Mechanical Drawing
Reference dimensions for gearbox mounting, shaft positioning and motor installation. The supplied drawing is marked KC-10BY25; its compatibility with the KC-GM12-10BY D-shaft configuration requires engineering confirmation.
Drawing Verification
The reference drawing includes gear and shaft details that may describe a different output configuration. Confirm the approved mechanical drawing, shaft extension, mounting dimensions and wire assignments before tooling or installation.
10mm Geared Stepper Motor Performance Advantages
- Gear Reduction Control: Multiple spur gear ratios allow output speed and theoretical step resolution to be matched to the motion requirements of the mechanism.
- Electrical Configuration Options: Different voltage and winding resistance options support integration with compatible bipolar stepper drivers.
- Mechanical Installation: The small geared stepper motor uses a defined gearbox mounting interface that can be evaluated during fixture and housing design.
- Output Shaft Selection: D-shaft and threaded shaft configurations provide different coupling arrangements for mechanical assemblies.
- OEM Configuration Support: Gear ratio, winding specification and shaft extension can be reviewed together against application load, positioning and installation requirements.
Motor Selection and OEM Customization
When selecting a micro geared stepper motor, gearbox ratio alone does not determine usable output torque. Motor winding characteristics, driver conditions, operating speed, gearbox efficiency and load duty cycle must be evaluated together.
Configuration Requirements
For an OEM quotation or sample evaluation, provide the required operating voltage, gearbox output speed, load torque, output shaft dimensions, mounting requirements, duty cycle and estimated order quantity. Kechen Motor can review the requested configuration against available manufacturing options.
Payment and Shipping
Payment
- T/T Payment: Bank transfer terms are confirmed through the quotation or proforma invoice before production.
- Sample Payment: Sample charges and payment arrangements are confirmed according to the requested motor configuration.
Shipping
- Air Shipment: Air freight or courier arrangements can be evaluated for samples and smaller consignments.
- Sea Shipment: Sea freight can be considered for production orders according to shipment volume and destination.
- Delivery Schedule: Production lead time, dispatch arrangements and transit estimates are confirmed for each order.
10mm Geared Stepper Motor Frequently Asked Questions
Q1. What Is the Difference Between the 5 V and 12 V Versions?
The 5v dc stepper motor and 12v dc stepper motor options require the appropriate winding and driver configuration. The available phase resistance must be matched to the selected voltage version. Final electrical specifications should be verified against the approved sample.
Q2. How Does the Gear Ratio Affect Output Step Resolution?
The nominal output step angle is calculated by dividing the motor step angle by the gearbox reduction ratio. Higher ratios reduce theoretical angular movement per motor step, but actual positioning accuracy also depends on gearbox backlash and mechanical loading.
Q3. Is the Listed Torque Available With Every Gear Ratio?
No. The stated torque range varies with gearbox ratio, winding configuration and operating conditions. Continuous usable output torque must be confirmed through configuration-specific data and sample validation.
Q4. Can the Output Shaft Be Customized?
The 3 mm D-shaft is the listed output configuration, while an M4 threaded shaft is an option. Shaft extension changes depend on mechanical feasibility and the selected gearbox assembly.
Q5. Which Stepper Driver Is Required?
The motor uses a 2-phase, 4-wire bipolar connection. Driver selection must account for the confirmed winding resistance, operating voltage, phase current and stepping requirements. The final wire-color assignment must be verified because the supplied technical documents differ.
Q6. Can the Mechanical Drawing Be Used Directly for Production?
The drawing should be treated as a reference until its compatibility with the selected KC-GM12-10BY variant is established. Mounting dimensions, shaft details and tolerances require confirmation through an approved drawing.
Q7. Is This Small Stepper Motor With Gearbox Suitable for OEM Assemblies?
The KC-GM12-10BY can be evaluated for small rotary mechanisms requiring geared stepper control. Suitability depends on the available installation space, required output torque, backlash tolerance, operating speed and duty cycle.
