Product Description:

The 68BM220BBR26 is a highly portable servo motor originally crafted and released by Denki Sanyo under the powerful ABS super servo line. Known for its square-cylindrical form factor, this compact servomotor combines power and portability. Like other servomotors, this product is not intended to have a direct connection with the mains supply. Instead, at all times, the 68BM220BBR26 must be connected to an appropriate servo amplifier. In servo systems, the servo motor is usually equipped with an encoder that allows the servo amplifier to monitor changes in the rotor speed, position, or both. As part of the ABS super series, this device can achieve a relatively high rated power.

Based on the product’s nameplate, the 68BM220BBR26 achieves the following rated values: 3.6 kilowatts and 2000 rev per min. For most servomotors, the rated values are attained at the nominal input voltage. Coincidentally, these rated values are also considered as continuous ratings, as opposed to intermittent ratings. Considering its compact construction and size, the 68BM220BBR26 has a high power-to-weight ratio. Aside from its nameplate characteristics, another unique feature of this servomotor is its holding brake. The holding brake can perform hold operations to prevent the rotor from moving with respect to some reference. Specifically, the 68BM220BBR26’s holding brake requires a nominal input voltage of 90 V.

As a rotary servomotor, the 68BM220BBR26 employs a smooth shaft, making it>> suitable for general-purpose applications. The 68BM220BBR26 also comes with a shaft seal, which prevents the intrusion of both dust, liquid, and other chemicals during operation. Considering its shaft seal and protective chassis, this product has a protection category of <. When purchased from Wake Industrial, this motor comes with a one-year warranty.
