Features:
- AC servo motor BSH 14.9 Nm 4000 rpm untapped shaft without brake IP50
- High power density, medium inertia three-phase AC synchronous servo motor
- It is primarily used in conjunction with Schneider Lexium 05 or Lexium 15 series drives and is widely used in automated production lines in industries such as printing, packaging, textiles, and material handling
The BSH1402P21A2A is a high-performance AC servo motor from Schneider Electric's Lexium BSH series. Designed for high-dynamic performance and high-intensity industrial automation applications, this motor has a standard flange diameter of 140 mm, a rated output power of 3.4 kW, and a maximum mechanical speed of 4000 rpm. It provides a continuous stopping torque of 14.9 N·m (up to 19.5 N·m at certain voltages) and maintains extremely high responsiveness during frequent reciprocating motion under high loads and high accelerations.
In terms of hardware configuration and electrical characteristics, this model exhibits extremely high precision and industrial-grade adaptability. It integrates a single-turn absolute encoder based on the SinCos Hiperface protocol (with a feedback resolution of up to 128 cycles/revolution), which can provide high-precision mechanical rotor position and speed feedback for compatible Lexium series servo drives, thereby eliminating system transmission errors.
The BSH1402P21A2A Schneider Electric AC servo motor may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

From a working principle perspective, the BSH1402P21A2A servo motor is primarily based on the electromagnetic induction principle and closed-loop vector control technology of a three-phase AC permanent magnet synchronous motor (PMSM). When the matched Lexium servo amplifier outputs a three-phase sinusoidal AC current modulated by pulse width modulation (PWM) and inputs it to the motor stator windings, a uniformly rotating alternating magnetic field is generated inside the stator.
The high remanence and high coercivity permanent magnets embedded inside the motor rotor attract each other with the rotating magnetic field of the stator, thus maintaining synchronous rotation and outputting strong mechanical power at the optical shaft end through reluctance torque.
During rotation, the SinCos absolute encoder at the tail end captures minute angular changes of the rotor in real time through photoelectric or magnetoelectric induction and feeds back the position data to the driver in the form of analog sine and cosine signals. The driver then uses this data to adjust the amplitude and phase of the high-frequency stator current, thereby achieving high-precision full closed-loop control of the "current loop-speed loop-position loop".
