Product Description:

The B3.SM.00A-4400 synchronous servo motor is produced by KEB as part of the SM Synchronous Servo Motors series. Designed for closed-loop motion systems, the unit converts electrical energy into precise shaft rotation, allowing automation controllers to regulate speed, angle, or torque according to process requirements. It can be used in compact axis drives that require fast response, stable positioning, and repeatable motion in assembly robots, material-handling gantries, and other dynamic industrial equipment.

The motor can deliver a maximum output torque of 17.71 Nm during short bursts, while a rated phase current of 3.6 A supports continuous operation. High-speed tasks are possible because the rotor can spin up to 10000 rpm before mechanical stress becomes critical. The back electromotive force rises in proportion to speed at 80.61 Vpk/1000 rpm, so the selected drive must account for this voltage increase at higher shaft speeds. Electrical response is influenced by a stator inductance of 18.8 mH, which affects current rise time and the rate at which torque can be modulated. These characteristics are important when matching the motor to a servo amplifier for rapid acceleration and deceleration cycles.

At standstill, the motor sustains 3.22 Nm of stall torque while drawing a stall phase current of 4.1 A, which is relevant for axes that must resist load without rotating. Short acceleration peaks are allowed up to 24.6 A of phase current, giving the drive temporary overload capacity without exceeding the motor's intended limits. Winding resistance is 3.9 Ω, which helps estimate heat generation during continuous duty and affects the voltage required to maintain current. The electromagnetic circuit uses four pole pairs, allowing servo drives to process more position updates per mechanical revolution and support smooth control with reduced torque ripple.
