Product Description:

Okuma’s BL Servo Motors series has launched its new variant BL-MC50E-20TB with advanced specifications. This model provides constant power during long running times as it has a continuous current of 40 A>. The motor is in the lower voltage category as it operates on a supported voltage range of 24V DC to 48V DC. Furthermore, it is capable of producing a < of 73 A which serves during the high demand moments. The motor accomplishes the swift movements needed for accurate operations while running at high speeds of approximately 2000 RPM.

The module integrates an incremental encoder with Hall sensors for precise feedback, critical for accurate motion control. Its cooling method relies on natural convection and simplifies thermal management without the need for forced cooling. Weighing 3.5 kg, this unit balances compactness with robust performance. It meets an IP20 protection class, ensuring basic protection against solid objects while remaining accessible for maintenance. This Okuma’s variant achieves a maximum mechanical speed of 7500 RPM, delivering high-speed operation when needed. Its interface supports RS232 and RS485 communication and allows seamless data exchange with controllers.

Moreover, it operates efficiently within an operating temperature range of –10°C to 60°C, guaranteeing reliable function under typical industrial conditions. Expanding on its advanced design, the BL-MC50E-20TB motor offers versatile mounting options, being both DIN rail and panel mountable, which facilitates flexible system integration. The control signal is managed via a PWM control input and enables fine modulation of the motor’s response. Safety is enhanced by built-in overcurrent and thermal shutdown protection to guard against operational faults. The device also supports EtherCAT as a digital communication protocol and provide rapid and robust network connectivity. An impressive operating life of 10,000 hours further attests to its durability and reliability.
