Product Description:

The P50B8040DXVT3E is a sturdy and efficient servo motor manufactured and designed by Sanyo Denki under the P5 motor series. Characterized by its balanced loading inertia and capacity, this servo motor is ideal for precise and small servo applications requiring a consistent driving speed. As a P5 motor, the P50B8040DXVT3E has a compact square-cylinder structure. Although it does not employ a set of cooling fans, this servo motor benefits from its efficient and compact design to dissipate heat naturally by air convection. To operate properly, this servomotor must be connected to an appropriate servo amplifier where it can draw power.

Servomotors, in general, operate in a closed-loop system. What makes them different from traditional motors is that servomotors usually need a controller that can adjust the speed, position, or torque, depending on some criteria. The servo amplifier performs all monitoring and adjustment functions for the motor. In servo motors such as the P50B8040DXVT3E, the feedback signal comes from the encoder. The built-in encoder in servomotors provides signals to the amplifier to represent the current state of the motor shaft. For P5 servomotors, there are two main encoder types: the incremental and absolute encoder.

The P50B8040DXVT3E has a maximum rotating speed of 4500 rpm. For most servomotors, the maximum rotating speed is obtained at rated torque conditions. Although this servomotor does not employ a holding brake, the connected amplifier can still perform stop and hold functions whenever necessary. As part of the P5 series, the P50B8040DXVT3E excels for high-power applications such as industrial machines and robotics. Like all other P5 servomotors, this machine can operate at an ambient temperature between 0 and 40 degrees Celsius.
