Product Description:

The BL-MT300M-20SN is an impressive AC servomotor released by Okuma Corporation under the BL product line. Boasting an optimized chassis design and form factor, this servomotor has efficient heat dissipation capabilities, making it perfect for sensitive industrial applications. Like other BL motors, the BL-MT300M-20SN runs at a nameplate frequency of 133 hertz and requires a terminal input voltage of 142 volts. It features a permanent magnet inside its core, allowing it to accelerate to the rated speed quickly. It employs a terminal box that protects the power connector ports and the built-in motor encoder. Whenever operated at the nameplate velocity, the BL-MT300M-20SN can also achieve its maximum torque and power.

In general, for AC motors, the maximum torque and speed cannot be achieved simultaneously. The BL-MT300M-20SN, in particular, can only supply its rated output torque at the maximum speed. Based on its nameplate, the rated velocity of the motor during operation is 2000 rpm. Assuming constant field and voltage excitation, the corresponding output power and current of the motor are 4.6 kilowatts and 21.5 A. Similar to other Okuma BL servomotors, the BL-MT300M-20SN can tolerate a maximum surface temperature of 155 degrees Celsius. Furthermore, because the motor relies on natural cooling, the thermal time constant of this machine is more than 30 minutes.

The BL-MT300M-20SN features a smooth keyless shaft, allowing it to drive general automation systems and loads. The motor’s shaft side also employs a sealing ring, which protects against the intrusion of foreign materials and moisture on the drive. Like most large servomotors, the BL-MT300M-20SN supports flange mounting and provides a total of eight screw holes for mounting the motor either on a fixed structure or other device.
