4pole High Torque Motor
By applying 4-pole magnet, effective magnet density area is enlarged, and the torque constant is greatly enhanced.
Features
Effective magnet density area: +30% (Orbray test result)
Total magnetic flux increased +30% from 2 pole magnet.
Torque constant: +60% (Orbray test result)
When running with the same road, current consumption is 35% less than 2-pole magnet motor.
Mechanical time constant: -60% (Orbray test result)
With enhanced torque constant, response speed is also improved by 40%.
As a pioneer in coreless motors, Orbray has pursued development of high torque motors. Generating high torque by enlarging the magnet or inputting a large current has its limitations in terms of heat generation and magnet materials. Orbray tried to increase torque by increasing number of magnet poles form 2 to 4.
By applying a 4-pole magnet, the effective magnet density area is enlarged. As a result, it contributed to a higher torque constant and low current consumption. Moreover, it enhanced mechanical time constant, so even the response speed became quicker.
Using diamond processing technology, a 4-pole magnet processing method has been established in Orbray.
