马达编码器编码器为现代AC马达能准确地监测转动的组分的状况的单位是重要的在许多应用。 现代AC马达要求编码器连续监测速度、自转的位置和方向。 These encoders, which are typically external to the motor, are exposed to environmental conditions, which in some cases can have a significant impact on service life.Integrated units from SKFSKF motor encoders (fig 1), however, are mechatronic units that combine sensor and bearing technology. Available for shaft diameters ranging from 15 to 45 mm, these encoder units are mounted directly inside the motor and require only 6 mm of extra space in the axial direction. The sensor body, impulse ring and bearing are mechanically attached to each other, forming a compact, integrated, ready-to-mount unit that is shielded from external influences. SKF motor encoder units, which can be installed on the drive or driven side of asynchronous motors, provide a medium resolution signal between 32 and 80 digital pulses per revolution. They can accurately detect speeds from zero to 20 000 r/min.
SKF sensor bearing units are used to accurately monitor the status of rotating or linear components. These units are:
Following is a brief overview of the sensor integrated solutions engineered by SKF. These solutions have been well proven in a variety of industrial and automotive applications such as electric motors, electric vehicles, road rollers, tractors, forklifts and conveyors.
Typical uses include:
