Product Description:
The 8JSA31.E5050D800-0 is a top-tier synchronous servo motor manufactured by B&R Automation under the exclusive 8JSA product series. Unlike other servo motors, 8JSA motors employ sinusoidal commutation alongside a high-resolution EnDat encoder. To operate at nameplate values, this servo motor must be configured in a star connection. Like other 8JSA motors, the 8JSA31.E5050D800-0 exhibits high overload capacity and dynamic profiles due to its low rotor inertia and optimized rotor design. Even without a built-in cooling system, this servo motor has excellent heat dissipation characteristics due to its well-designed motor housing and flange. When connected to an appropriate three-phase power supply, this AC machine achieves a nominal speed of 5000 rpm.
At the rated shaft velocity, the 8JSA31.E5050D800-0 achieves the following nameplate values: 0.95 Nm, 497 watts, and 1.12 A. Even though this servo motor has a nominal speed of 5000 rpm, it can be operated up to a maximum shaft speed of 8100 rpm safely. At this speed, however, the motor typically reaches a subnominal torque value. When operated at speeds lower than the nominal value, it is possible to increase the shaft torque output of the motor. Particularly, at optimized conditions, this three-phase machine can achieve a peak torque of 4.5 Nm.
As a relatively small synchronous motor, the 8JSA31.E5050D800-0 has a short thermal time constant, allowing it to achieve steady-state temperature faster. Another unique feature of this servo motor is its standard holding brake. During operation, the holding brake can hold the rotor in place at a maximum torque of 2.5 Nm. Considering the brake, the total mass of the product goes up to 2.5 kilograms. Wake Industrial offers a warranty with a validity of one year upon purchase of this motor.
