Product Description:

The MS2E03-B0BYN-CMSK0-NNNNN-NN is a compact 3-phase permanent-magnet motor from Bosch Rexroth Indramat's MS2E Synchronous Servomotors series. It is intended for fast point-to-point motion in pick-and-place units, gantries, and auxiliary axes where cabinet and cable space are limited. The design supports precise servo control while keeping the motor package small for very dense machine layouts.

Rated output reaches 0.21 kW, and rated torque is 0.35 Nm under the stated thermal rise. A nominal speed of 9000 min⁻¹ supports short indexing cycles and light conveyor duties. Peak current rises to 7.25 A for brief acceleration demands, while the encoder supplies 20-bit single-turn feedback with 4096 absolute revolutions for startup without homing.

Maximum torque reaches 3.75 Nm, giving the motor reserve for short overload events beyond continuous operation. The housing carries an IP65 rating, and the keyway shaft uses a sealing ring to help resist dust and water during normal service. Inductance of 20.22 mH and phase resistance of 14.3 Ohm help match the motor to a suitable drive, while the low-inertia rotor, deep-groove ball bearings, self-cooling, PT1000 sensor, and single rotatable M23 cable support stable high-speed operation.

Wake Industrial stocks this servomotor and offers same-day shipping on qualified orders. Quotations remain valid for 30 days, which helps buyers coordinate approval timing for planned replacements. Each purchase includes a 1-year warranty, and the chat tool available on the website can be used for general questions about type codes or fault codes. This reduces delays when failed axes must return to service very quickly.
