Coreless Micro DC Motor

 

VSD offers Coreless Micro DC Motors, which are the industry's leading choice for their excellent performance and wide range of applications. Our products cover two series, brushed and brushless, to meet different customer needs. Self-adhesive enameled wire is used as the core material of the motors, the coils can be bonded and molded after heating or solvent treatment, and the winding-less core design enables the efficiency to reach a high level of 80%-90%.

 

In response to customers' diverse needs for appearance, VSD supports body customization, including electroplated blue zinc (salt spray test 24H, internal test 36H or more), electroplated colored zinc (salt spray 48H, internal test 72H), nickel plating (elegant appearance, average salt spray effect), electrophoresis/spraying (black, salt spray 48H, complex process), and electroplated zinc-nickel alloy (excellent resistance to salt spray, highest price). In addition, the motor's bearings can also be customized, with options covering oiled bearings, powder metallurgy bearings, and ball bearings, and supporting a wide range of materials: iron-based (hard, wear-resistant, and louder), iron-copper-based (hard, wear-resistant, and a little less loud), and bronze-based (soft, not wear-resistant, and with excellent sound performance).

 

In brushed series, we use high quality brushes to meet different performance requirements, in which we use carbon crystal made in China for normal quality, and imported carbon crystal (such as Fuyong, a Japanese brand) for high quality. For brushless series, our driver boards optimize the control program and electronic components to achieve a variety of functions: current regulation, PWM speed control, CW/CCW forward/reverse rotation control, and FG signal feedback and many other technical supports. Meanwhile, the terminals of brushless motors can be flexibly adapted according to customer requirements to ensure better compatibility.

 

Our Coreless micro DC motors can also be integrated with planetary gearboxes or magnetic encoders for closed-loop control, taking the technical applications to the next level. The motors perform particularly well in systems that require fast response, such as precise adjustment of missile flight direction, fast response of camera autofocus, industrial robot motion, and bionic prosthetics. In toy cars, aeromodels, electric toothbrushes and other commodities that are limited in size, VSD hollow cup motors are also able to fit perfectly, providing customers with efficient and stable power support.

 

By choosing VSD's Coreless Micro DC Motors, you are getting a high-end product with excellent performance, flexible customization, and a wide range of applications. We look forward to providing the optimal solution for your project.

 

 

Advantages of Coreless Micro DC Motor

 

Dramatic increase in efficiency due to coreless design

VSD's Coreless miniature DC motors feature a coreless design that completely avoids the eddy-current losses associated with conventional winding cores, resulting in efficiencies as high as 80%-90%, far exceeding the conventional brushless motors' efficiency of about 60%. This high-efficiency design provides customers with better performance and stands out especially in high-precision, high-efficiency applications.

 

Low rotational inertia for faster power response

The hollow cup structure greatly reduces the rotational inertia of the motor and eliminates the power loss caused by eddy current in the iron core. This makes the motor perform more outstandingly in the process of rapid acceleration and deceleration, and the fast power response under large torque provides a reliable guarantee for complex working conditions.

 

Low current consumption for better energy saving

Thanks to the unique coreless design, the current consumption of the motor is significantly reduced. This feature makes Coreless motors ideal for battery-powered scenarios, such as small drones, portable devices, etc., which can effectively extend the endurance of the device and improve the efficiency of use.

 

Lightweight design for high dynamic demands

Lightweight is a key feature of Coreless Micro DC Motors. The motors are lighter and have lower inertia, resulting in faster response speeds, making them ideal for fast-response scenarios, such as automation control systems, precision instruments, and other fields.

 

High-quality materials for long-lasting durability

VSD's Coreless motors utilize a combination of high-quality materials and advanced manufacturing processes to ensure superior durability and long life. It maintains consistent performance over long periods of operation while reducing maintenance costs, providing long-term value to the user.

 

Flexible customization to meet diverse needs

To accommodate a wide range of application scenarios, VSD offers a comprehensive customization service. Whether it's size, material, or special performance needs, we can tailor the most suitable solution to the specific requirements of our customers, ensuring flexibility and versatility.
