750W AC Servo Motor

In the model selection of AC servo motor, the motor power, revolving speed, voltage, insulation class and so on must be taken into account. Many users are unfamiliar with these parameter requirements before model selection. As a industrial AC servo motor manufacturer, ATO can help users to select the most appropriate motor model. And we will introduce a high quality and high precision AC motor with 1 hp (750W) power rated, 3000 rpm speed.

Many servomotors with high torque suffer from high braking torque (unenergized servomotors want to lock in certain positions more than others). They also often have significant distortions in their reaction potential characteristics, so even the best AC sine wave servo drives will inevitably produce torque ripple. These torque defects cause vibration and noise, affecting settling time performance and inducing servo seek. Smooth, quiet motion requires brushless servomotors with low torque moments and linear, low-pulsation torque output. Rotor balance and bearing quality are also important, especially at medium and high speeds.

The magnetic design also has a significant impact on the noise and vibration of the motor. Over the past few years, it has become fashionable to use internal permanent magnet (IPM) rotor designs in servo motors in order to reduce costs.IPM designs concentrate the permanent magnetic flux by burying the permanent magnets in a laminated stack on the rotor shaft. Flux focusing allows the use of smaller and/or lower energy magnets, however, it can lead to large changes in inductance of the motor as it rotates, resulting in poor servo performance. It also induces pulsating, non-tangential forces within the motor, which can cause significant audible noise and vibration.
