Brushed dc coreless motors have air core armatures, so they can reach high speeds in a matter of only milliseconds with about 90% efficiency.
Compared to conventional iron-core, brush-type dc motors, the ironless types have no iron losses, low friction, and acceptable thermal dissipation, which make them extremely efficient. The design of the low-inertia rotor is the key to rapid acceleration and fast reaction time. In addition, their linear torque-speed characteristics fit well with simple drive circuits. They should be especially considered when designing low-power, battery-operated equipment, such as pagers, model trains, and hand-held tools.

The name coreless (or ironless) refers to the motor construction. These motors, unlike most other types of motors, have no iron core-armature in the rotor. Special skewed or honeycomb patterns are used to wind the rotor coils to ensure mechanical strength and evenly distribute the magnetic flux for all coils in the rotor winding. This results in maximum torque and smooth rotation. Because it has no iron core to support the windings, they are typically held together by epoxy. Some designs use a plastic frame. Depending on the rotor geometry, ironless motors can be cylindrical or disc shaped. The stator is often made of samarium-cobalt, or Neodymium magnets.

FAQ 

1Q:What is your terms of delivery?
A: We accept EXW,FOB,CFR,CIF,etc. You can choose the one which is the most convinent or cost effective for you.
2Q: Can I get some samples?
A: It depends. If only a few samples for personal use or replacement, I am afraid it will be difficult for us to provide, because all of our motors are custom made and no stock available if there is no further needs. If just sample testing before the official order and our MOQ, price and other terms are acceptable, we'd love to provide samples.
3Q: How long should I wait for the feedback after I send the enquiry?
A: Within 12 hours.
4Q: Can i be your company sale agent in our market?
A:Yes,we will depend on the sales turn over and also do research on your market. Please contact with our sales person for details.
5Q:What is your terms of payment?
A:Accept 100% in advance for sample.For regular orders,we prefer 30% deposit in advance,70% before shipment.
6Q: What is your MOQ?
Our MOQ is 2000pcs. But at the beginning of our business, we accept small order.
7Q: How much is the packaging size?
A: Packing size is in accordance with your order, your product specifications to determine the package size.
Coreless motor planetary reducer with other reducer does not have the characteristics of high energy conversion (low energy consumption, high efficiency), start, fast braking, fast response, mechanical time constant is less than 28 milliseconds, planetary reducer can reach 10 milliseconds , The operation stability is very reliable, the speed fluctuation is very small;
