China OEM Electric Scooter Mask Factories – Minimotors – Nanrobot

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.

Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless, may be of various phase (see single-phase, two-phase, or three-phase), and may be either air-cooled or liquid-cooled. General-purpose motors with standard dimensions and characteristics provide convenient mechanical power for industrial use. The largest electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives. Small motors may be found in electric watches. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction.

Electric motors produce linear or rotary force (torque) intended to propel some external mechanism, such as a fan or an elevator. An electric motor is generally designed for continuous rotation, or for linear movement over a significant distance compared to its size. Magnetic solenoids are also transducers that convert electrical power to mechanical motion, but can produce motion over only a limited distance.

Electric motors are much more efficient than the other prime mover used in industry and transportation, the internal combustion engine (ICE); electric motors are typically over 95% efficient while ICEs are well below 50%. They are also lightweight, physically smaller, are mechanically simpler and cheaper to build, can provide instant and consistent torque at any speed, can run on electricity generated by renewable sources and do not exhaust carbon into the atmosphere. For these reasons electric motors are replacing internal combustion in transportation and industry, although their use in vehicles is currently limited by the high cost and weight of batteries that can give sufficient range between charges.

1. What services can Nanrobot provide? What is the MOQ?
We provide ODM and OEM services, but we have a minimum order quantity requirement for these two services. And for European countries, we can provide drop shipping services. The MOQ for a drop shipping service is 1 set.

2.If the customer places an order, how long will it take to ship the goods?
Different types of orders have different delivery times. If it is a sample order, it will be shipped within 7 days; if it is a bulk order, the shipment will be completed within 30 days. If there are special circumstances, it may affect the delivery time.

3.How often does it take to develop a new product? How to obtain new product information?
We has been committed to the research and development of different types of electric scooters for many years. It is about a quarter to launch a new electric scooter, and 3-4 models will be launched a year. You can continue to follow our website, or leave contact information, when new products are launched, we will update the product list to you.

4.Who will deal with warranty and customer service in case it has issue?
The warranty terms can be viewed on the Warranty & Warehouse.
We can help deal with after-sales and warranty that meet the conditions, but customer service needs you to contact.
