Question 1

Standard models typically ship faster with a lower MOQ, while fully customized motors require engineering review and tooling, which affects both MOQ and lead time. Contact us with your specifications for an exact quotation.

Accepted Answer

The Short Answer For standard catalog motors, MOQ is typically low and lead time is short. For fully customized motors, MOQ and lead time depend on the engineering changes required, tooling needs, and order quantity. The fastest way to get an exact figure is to send your target specifications so our engineers can review them. How MOQ and Lead Time Are Determined Customization LevelTypical MOQTypical Lead Time Standard modelLow, single units possibleShort, stock or quick production Parameter change (voltage, encoder, winding)ModerateMedium, production scheduling Structural customization (shaft, flange, bore)HigherLonger, includes tooling and validation How the Process Works Send specifications: torque, speed, voltage, encoder type, dimensions, and target quantity. Engineering review: our team confirms feasibility and proposes the optimal motor and reducer combination. Quotation: you receive MOQ, lead time, and pricing in writing. Sampling: samples are built and validated before mass production. Tip for Faster Quotation The more complete your specification sheet is, the faster we can quote. If you are unsure about parameters, our engineers can help you define them based on your application. Contact Us for a Quotation

Question 2

Match torque, speed, encoder resolution, voltage and form factor to your robot's joint loads and motion profiles. Always compare continuous torque at operating speed, not just peak torque, and account for the reducer ratio and inertia.

Accepted Answer

The Short Answer Start from your robot's joint loads and motion profiles: calculate the continuous torque and peak torque required at the operating speed for each joint, then select a motor and reducer combination that delivers both with margin. Compare continuous torque at working speed rather than stall torque alone, and verify encoder resolution, voltage, and mechanical envelope before finalizing. Selection Steps Define the load: list the mass, center of gravity, and required angular acceleration for each joint of your robot. Compute torque: calculate continuous and peak torque, then add a safety factor of 1.3-2x for dynamic loads. Check the speed: confirm the motor speed after the reducer meets the joint's maximum angular velocity. Choose the encoder: pick resolution based on positioning accuracy, e.g. absolute encoders for humanoid joints. Verify integration: confirm voltage, current, controller compatibility, and available space for the housing and cabling. Common Pitfall Peak torque is only available briefly. If the rated continuous torque is lower than the sustained load, the motor will overheat during continuous operation. Always size for continuous torque first, then confirm the peak capability covers transient motions. Send Us Your Robot Joint Requirements

Question 3

A hollow-shaft motor has a bore through the rotor for cables, shafts or optics to pass, while a solid-shaft motor uses a conventional output shaft. Hollow-shaft designs save space, simplify wiring and reduce height in compact robotic joints.

Accepted Answer

The Short Answer A hollow-shaft motor has a bore running through the center of the rotor, so cables, shafts, or optical elements can pass directly through the motor. A solid-shaft motor transmits motion through a conventional output shaft instead. Hollow-shaft designs are preferred in compact robotic joints because they save axial space, simplify cable routing, and eliminate the need for external cable management. Key Differences at a Glance FeatureHollow-Shaft MotorSolid-Shaft Motor Center boreYes, cables or shafts pass throughNo, solid rotor core Axial heightCompact, ideal for thin jointsRequires external cable routing space Wiring complexityReduced, cables stay inside the jointHigher in multi-axis assemblies Typical useHumanoid joints, robotic arms, gimbalsGeneral servo and drive applications When to Choose Each Type Choose a hollow-shaft motor when joint height is limited and cables must pass through the axis of rotation. Choose a solid-shaft motor when a standard coupling or pulley mount is simpler and through-axis routing is not needed. For multi-axis arms, hollow-shaft motors keep wiring organized and reduce failure points from cable strain. Browse Our Motor Range
