The brushless motor "IPM Series" from Meiwa Manufacturing is an embedded magnet type (IPM) motor that incorporates permanent magnets in the rotor. Since it does not have mechanical contacts (brushes and commutators), which are drawbacks of DC motors, there are no issues with insulation, voltage resistance degradation, or external contamination caused by brush wear particles. Additionally, it offers many advantages over brushed motors, including energy efficiency, long lifespan, compact size, lightweight, low noise, and maintenance-free operation. We are currently offering a free booklet that provides useful information on various types of motors and their corresponding characteristics, spanning a total of 50 pages! [Design aids include design diagrams and standard characteristics for each product] - IPM motors - Commutator motors - DC magnet motors - Power units and commutator geared motors - External rotor permanent magnet generators - High-speed SR motors - Aluminum die-cast products - Small gears *For more details, please download and view the PDF.

• PM motor

This is an embedded magnet type (IPM) motor with permanent magnets embedded in the rotor. 【Features】 ■ There are no mechanical contacts (brushes and commutators), which are drawbacks of DC motors, so there are no issues with insulation, voltage resistance reduction, or external contamination due to brush wear particles. ■ Compared to brushed motors, it offers many advantages such as energy efficiency, long lifespan, compact size, lightweight, low noise, and maintenance-free operation. ■ Since the magnets are embedded in the rotor, there is no risk of centrifugal separation of the magnets, making it mechanically safe. ■ By utilizing both magnetic torque and reluctance torque, it enables high torque and high power operation. ■ It can be adapted to a variety of applications with microcontroller control. ■ Products can be customized according to customer requests, including voltage, rotation speed, gear reduction, and various shapes. *For more details, please feel free to contact us.
