Non-iron core, high-precision coil with a distinctive design
High-performance rare-earth magnets, providing high power density
High torque, efficiency, and low noise, with a stable service life
Smooth operation and rapid response
Low temperature rise ensures motor stability
The 22D X 30L DC Coreless Motor 12V, 11000 RPM has outstanding characteristics of energy efficiency, control and driving, including:
1. Energy efficiency characteristics: the energy conversion efficiency is very high, with a working efficiency of generally more than 70%, and some products can even reach more than 90% (in comparison, iron core motors are generally 20-50%).
2. Control characteristics: rapid starting and braking, extremely fast response, with a mechanical time constant of less than 28 milliseconds, and some products can even reach less than 10 milliseconds (iron core motors are generally more than 100 milliseconds); Under the high speed operation condition in the recommended operation area, the speed can be adjusted sensitively and conveniently.
3. Driving characteristics: the operation stability is very reliable, and the fluctuation of speed is very small. As a micro motor, its speed fluctuation can be easily controlled within 2%.
In addition, the energy density of the coreless motor has been greatly improved, and its weight and volume have been reduced by 1/3 to 1/2 compared to an iron core motor with the same power.
All the technical features of this product series developed by our company have reached the same level as those of Maxon and Faulhaber. It is widely used in medical treatment, testing, handheld instruments, intelligent robots, precision automation, aerospace, extreme temperature instruments, industrial and mining operation equipment, and other industries.

Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
While the same return policy applies, these orders require a separate contact process for returns.
RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
