Product Description:
B & R Automation a business renowned for producing high-performance industrial automation components, is the manufacturer of the product 8LSA53.DB022S900-3 Synchronous Motor. This motor is made for motion applications that require accuracy and efficiency. It operates at a nominal speed of 2200 rpm and provides an operating torque of 4.2 Nm.
The 8LSA53.DB022S900-3 Synchronous Motor delivers a nominal power of 968 W and draws a nominal current of 1.9 A. The torque reaches 4.5 Nm under stall circumstances, and the equivalent stall current is 2 A. The motor’s maximum speed capability is 9000 rpm which makes it suitable for dynamic load requirements. At peak load, it can produce up to 13.8 Nm torque while handling a maximum current of 8 A. The synchronous motor torque constant is rated at 2.22 Nm/A which confirms accurate torque control. It also features a voltage constant of 134.04 V/1000 rpm that supports efficient back EMF generation. The motor's controlled electrical behavior is facilitated by the stator's measured resistance of 10.9 ohms and inductance of 95.92 mH. With an electrical time constant of 8.8 ms the motor responds quickly to control signals. It is engineered to deliver stable performance under continuous and peak load scenarios. Four pole pairs on the motor provide for steady and seamless motion control.
The 8LSA53.DB022S900-3 Synchronous Motor has a 33-minute heat responses constant for reliable operation under thermal load. The rotor's moment of inertia is 3.62 kgcm² which enables stable speed transitions and load handling. The motor weighs 6.2 kg without the brake for compatibility in compact system designs. The 8LS Synchronous Motors offer a well-balanced specification set for industrial automation.
