Product Description:

The BL-MQ25E-20TB is an AC servo motor manufactured by Okuma as a member of the BL Servo Motors series. Designed for axis drives in industrial automation, it interfaces with matching amplifiers to translate numerical control commands into precise rotational motion. The compact construction and electronic commutation allow the motor to follow rapid speed or position references while maintaining constant torque output, making it suitable for CNC tool turrets, gantry loaders, and pick-and-place units that operate around the clock.

The motor’s continuous power rating is 0.5 kW, which indicates the mechanical energy it can supply at the shaft without exceeding its thermal design. To sustain that output, the windings draw a nominal phase current of 2.96 Arms, so conductors and protection devices must accommodate this steady-state demand. During rapid acceleration or transient load spikes, the associated amplifier may deliver up to 13.0 A, which provides short-term torque reserve while limiting overheating. Magnetic polarity is established by a 4-pole rotor, so the commanded electrical frequency directly determines the mechanical speed through the relationship between pole count and synchronous rpm. The unit is intended to run with a matching 30D drive module, ensuring parameter compatibility for current loops and regenerative braking functions.

Position feedback is provided through an E/F Type incremental encoder, allowing the drive to close velocity and position loops with sub-millisecond updates. A factory-installed jumper in the Connect position simplifies wiring because the feedback, power, and shield grounds are pre-bridged inside the terminal block. When the motor is paired with Okuma controls, configuration files automatically recognize the motor within the BL Servo Motors family, so only fine-tuning of gains remains.
