ZHAOWEI provides custom engineering to design gear motors utilizing DC motor, brushed motor, BLDC motor, and stepper motor products to meet customer-specific performance requirements for applications. And ZHAOWEI is an ISO 9001:2015 trusted designer and manufacturer of miniature, cost-effective.
Miniature Small Electric Motors
Our products find the right drive solution for your project in our product range of miniature and micro drive technologies - whether as a standard system or as a component that is tailored to your individual project requirements. For standard applications, ZHAOWEI offers a range of micro drives with a diameter of 3.4 mm up to 38 mm. The planetary gears are combined with direct current motors (DC motors), brushless motors or stepper motors
A planetary gearbox is a commonly used reducer consisting of the planet gear, sun gear, and outer ring gear, whose structure has the functions of shunting, deceleration and multi-tooth meshing to improve the output torque, better adaptability, and work efficiency. The sun gear is usually placed in the center, and the planet gears orbit around the sun gear, receiving torque from it. The outer ring gear (refers to the lower housing) meshes with the planet gears.
ZHAOWEI DC motors are high-quality DC motors, equipped with powerful permanent magnets. The centerpiece of the motor is the worldwide patented ironless rotor. This means outstanding technology for compact, powerful drives with low inertia. Thanks to the low mass moment of inertia, the DC motors have a very high acceleration.
High-performance in the smallest of spaces – the ZHAOWEI portfolio today spans from 4-pole servomotors for high torques to highly efficient flat motors and extremely small brushless DC micromotors.
Thanks to their special design, brushless motors from ZHAOWEI are ideal for use in high-performance applications in overload or continuous operation with very high service life requirements.
Diameter: 16, 20, 24, 28, 37 mm; Power: 0.01-40W; Output speed, gear ratio, output torque could be customized according to different needs. Spur gearbox is supported by the porous bearing, which has longer service life and lower noise under the same working condition.
For demanding positioning tasks that require a high level of accuracy, stepper motors are generally used.
Robust assembly, high-speed range, and exceptional performance in even the harshest environments make ZHAOWEI drive systems the perfect solution for demanding positioning applications. They are available with a wide variety of modular servo components such as encoders, low backlash gearheads, or integrated lead screws.
The brushes used in coreless DC motors can be made of precious metal or graphite. Precious metal brushes (silver, gold, platinum, or palladium) are paired with precious metal commutators. This design has low contact resistance and is often used in low-current applications. When sintered metal graphite brushes are used, the commutator is made of copper. The copper-graphite combination is more suitable for applications requiring higher power and higher current.
ZHAOWEI provides a set of customization services, from design, sampling, production, to testing, etc. Here are some specification ranges: diameter: 3.4mm-38mm, voltage: under 24V, output power: under 50W, output speed: 5rpm-2000rpm, speed ratio: 5-1500, output torque: 1.0 gf.cm -50kgf.cm.
