Product Description

As a global brand, Okuma designs world-class factory automation products that can be customized to suit different applications in different locations. Its product portfolio includes equipment like CNC machine tools, lathes, machining centers, grinders, and CNC controls. Okuma is also the designer and manufacturer of the BL servo motor series. It is a family of efficient three-phase servo motors constructed with varying speeds and torques.

The BL-MS50E-20T-1 is one of the AC servos motors in the BL series by Okuma. This motor has a tapered output shaft of 18.7mm to 22mm and works with an encoder model of the ER series by Okuma. Its nominal speed rating is 2,000 revolutions per minute while its stall torque value is 5.4Nm. It features 4 poles and is operated with a nominal connecting voltage of 166V. This BL three-phase AC servo motor model also requires a frequency of 67Hz and has a current rating of 4.3A. In compliance with the NEMA standard, it belongs to insulation class F. Hence, the maximum permissible temperature of its winding insulation is 155^oC.

The vibration level of the BL-MS50E-20T-1 must be checked regularly to prevent damage due to thermal overload. It is checked by monitoring the level of lubricant grease in the motor’s bearings. The vibration rating specified for this model must also be strictly complied with the IEC motor frame size of the motor is 34-1 and its continuous output power rating is 1kW. At the site of the operation of this motor, the ambient temperature must be maintained between 0^oC and 40^oC. Its interior should also be protected from damaging chips, coolants, and lubricating oils.
