Product Description

The B-204-B-21-B2 is a servomotor model by Kollmorgen, a renowned company that offers drives and motors for a wide variety of PLC and robotics applications. This servomotor represents the popular Goldline series. This series has a wide range of synchronous motors on offer, including low-inertia models, medium-inertia models, and explosion-proof models. When combined with SERVOSTAR certified servo amplifiers, Goldline servo motors deliver exceptional performance. Moreover, these motors are UL recognized.  

The B-204-B-21-B2 synchronous motor by Kollmorgen can be a great low-speed alternative for robotics as well as applications aimed at high accuracy. Operating on just 230 volts with VMax peaking at 250 V, the brushless synchronous motor can generate 2.1 HP power. This robust servo motor produces continuous stall torque of 4.7 N-m and can reach up to 13.8 N-m, when necessary. Compared to the power and torque, the 6.2 kilograms weight makes it a lightweight yet powerful servo motor. Moreover, durable construction and a powerful B winding are other positives aspects. Talking about construction, the B-204-B-21-B2 servo motor features a sealing that meets IP65 protection standard. And to ensure smooth operation, the servo motor features over-the-top insulation material that can withstand temperatures up to 180 Celsius.

The B-204-B-21-B2 brushless servo motor is maintenance-free and can be used in areas where continuous operation is required. Its brushless feature eliminates concerns on brush replacement from time to time. The heavy-duty shaft with a 14-mm diameter is 30 mm long, and to make it more durable, it has an extension from the rear end of the motor. The servo motor features a 4-pole pair design, which is accepted universally.
