AC Servo Motor Manufacturer
Our brushless and brushed small AC servomotors are flexible, application-oriented and meet the most stringent quality standards in the drive technology industry. They work well on both simple (1 or 2 axes) and complicated (up to 256 axes) applications.
In addition to the typical servo motor, we may also provide you specially made substitutes:
- Size: 80*50*50mm - 400*200*200mm, .etc
- Power Rating: 100W - 10KW
- Torque Range: 0.5 Nm to 100 Nm, .etc
- Cooling Method: Air-cooled or Water-cooled
- Phase: Single - phase, 2 phase, 3phase ac servo motors
Alternating Current(AC)
- Operates on AC power (single-phase or three-phase).
- Uses alternating current with sinusoidal waveforms.
- Electronic commutation via AC servo drive and inverter.
- Frequency of AC supply controls speed (via inverter).
- Smoother torque due to sinusoidal current control.
By Rotor Type
Our AC servo motor offers asynchronous and synchronous rotor types for either robust durability or high-precision, efficient, slip-free performance.
Asynchronous
- Necessary for torque, causing slight rotor and field speed difference.
- Generally more robust and capable of handling harsh environments.
- Simpler control but less precise than synchronous motors.
Synchronous
- The rotor synchronizes with the stator field for precise control.
- Excellent speed and position control for precision applications.
- Higher efficiency as there is no slip-related loss.

FAQ
What distinguishes a DC servo motor from an AC servo motor, in particular?
AC servo motors offer efficient, precise, high-speed performance. DC servo motors provide high starting torque, simpler control, but need more maintenance.
How does the price of an AC servo motor compare to that of a DC servo motor?
Generally speaking, AC servo motors are more expensive than DC servo motors because of their intricate design, sophisticated control systems, and increased accuracy.
What factors should be considered when choosing between an AC servo motor and a DC servo motor for an application?
Consider performance requirements (efficiency, precision), price, maintenance needs, power requirements, and application specifics such as load conditions and control complexity.
What are the typical applications for AC servo motors?
AC servo motors are used in industrial automation, robotics, CNC machines, renewable energy, and high-precision machinery.
Why might a 750W DC servo motor be preferred over an AC servo motor in certain applications?
A 750W DC servo motor is preferred for its low cost, simple control, high starting torque, and suitability for small-scale applications.
What are the maintenance requirements for DC vs. AC servo motors?
AC servo motors require less maintenance due to no brushes. DC servo motors need regular maintenance for brushes and commutators.
