Estun EMJ-10APB22 EMJ Series AC Servo Motor
1kW 200VAC Medium Inertia, 3000 RPM, 300% Overload Capacity, 2500 P/R Encoder, With Holding Brake, IP65
Product Overview
The Estun EMJ-10APB22 is a high-performance AC servo motor from Estun's renowned EMJ series. This 1kW (1000W) model features a medium inertia rotor design and is equipped with a holding brake, making it particularly suitable for vertical axis applications and systems requiring position holding when power is removed.
The EMJ series represents Estun's medium-inertia servo motor line, engineered for high-speed driving of mechanical feed axes in demanding industrial environments. With a standard IP65 construction rating and 300% peak torque overload capacity, the EMJ-10APB22 delivers exceptional power density and dynamic response for a wide range of automation applications.
Please Note: The "B" in the model suffix indicates this unit includes a 24V DC holding brake, a critical feature for vertical axis applications where load holding is required when the servo is disabled.
