I came across this question on a forum today. I found it quite interesting. As someone with 18 years of work experience, I’d like to briefly share some of my thoughts.<\/p>\n
First of all, let me get straight to the point:
\nThere is NO threshold such as “how many watts counts as a servo motor”! A servo motor is defined by its control type (closed-loop + encoder feedback system), not by its power rating. Servo motors range from a few tens of watts to several hundred kilowatts.<\/p>\n
I. Common servo power ratings on the market (industrial mainstream AC servo, 220V)
\n– 50W, 100W: Micro low-voltage servos, small precision mechanisms
\n– 200W, 400W: Small equipment, modular systems, robotic arms (most commonly used)
\n– 750W (0.75kW): The most popular specification for automated production lines
\n– 1.0kW, 1.5kW, 2.0kW, 3.0kW: Medium-load applications
\n– 4kW\u201315kW: Machine tools, large robotic arms, injection molding auxiliary equipment
\n– Above 15kW (380V high-power servo): Large equipment, presses, spindle servos<\/p>\n
II. The most easily confused key points<\/p>\n
Misconception: Only motors above 750W are servos; small-wattage ones are all steppers.
\nThis is incorrect. 200W and 400W servos are also very common. Stepper motors generally do not specify a rated wattage; they are mainly rated by holding torque (N\u00b7m).<\/p>\n
To distinguish between servo and stepper, look at these two points, not power:<\/p>\n
– Servo motor: Comes with an encoder (closed-loop feedback), paired with a servo drive, and its nameplate specifies rated power (W\/kW)
\n– Stepper motor: Mostly open-loop, its nameplate only specifies holding torque (N\u00b7m) and current, not rated power<\/p>\n
III. Here are some daily selection tips for non-standard automation:
\n– Lightweight modules, small pick-and-place units: 200W \/ 400W servo
\n– Conventional conveyors, small-load rotary mechanisms: 750W servo
\n– Heavy-duty slides, material handling mechanisms: 1.5kW, 2kW, and above<\/p>\n
