Product Description:
The BL-MC140J-20T is a three-phase Servo motor designed to meet IEC 34 requirements. Cooling fins are used to maintain a constant temperature while running constantly. The motor includes an OKUMA ER-J-7200D encoder for precise feedback and a persistent magnetic field.
The stall torque of this BL-MC140J-20T motor is 3.7 N·m, and it features an 8-pole configuration. The winding connection is set up in a Y-shaped configuration. The insulation class is F, which means it supports thermal endurance and can be reliably used. Rectangular in shape, the motor housing has a matte black finish and heat-dissipating cooling fins on top. There are several bolt holes in the metallic silver flange mounting plate, and it has some minor oxidation from usage. In order to provide a tight connection, the cylindrical shaft is made of metal and has a keyway that ends in threads. Two metal screws fasten the power connection, which consists of a big circular 4-pin connector and a smaller multi-pin connector for the encoder's feedback. A contributing factor to the smooth operation is the balanced phase currents supported by the star winding connection.
The BL-MC140J-20T servo motor is ideal for industrial automation applications that require precise control over speed and torque. The constant magnetic field allows users to complete more tasks with less effort and more torque. It produces 2.8 kW of continuous output power while rotating at 2000 rpm. The operating voltage is 133 volts, the current rating is 12.5 amps, and the frequency is 133 Hz. The inbuilt OKUMA encoder ensures accurate speed and location monitoring. Connectors made for industrial cable dependability and a flange for stable mounting are part of the motor's sturdy mechanical construction.
Frequently Asked Questions about BL-MC140J-20T:
Q: Why does BL-MC140J-20T use an 8-pole design?
A: An 8-pole design reduces speed to 2000 rpm at 133 Hz frequency. It improves torque output and smooth operation.
Q: Does the BL-MC140J-20T have a permanent magnetic field?
