Product Description:
The 8JSA32.R0030D700-0 Synchronous Motor provides a nominal output power of 569 W for steady performance during continuous-duty applications, and it is made by B & R Automation. This motor runs at a nominal speed of 3000 rpm with an ability to achieve a top speed of 8100 rpm to accommodate various speed applications without performance degradation.
The method of cooling in the 8JSA32.R0030D700-0 motor is self-cooling, and no external cooling system is required. In structural terms, this motor features a keyed shaft end with an oil seal, which improves torque transmission reliability and keeps the seal intact in harsh environments. Protection-wise, this synchronous motor complies with EN 60034-5 in terms of an IP65 rating, which offers full protection from dust entry as well as from low-pressure water jets in any direction. This motor also supports transportation in damp conditions, withstanding relative humidity of up to 90%, non-condensing, to guarantee its stability throughout logistics and storage. This motor without a brake weighs 2.23 kg, which is compact and easy to implement within systems with spatial constraints. The 8JSA32.R0030D700-0 synchronous motor also has a thermal time constant of 17 minutes for uniform heat dissipation under long operation without thermal overload.
This 8JSA32.R0030D700-0 synchronous motor incorporates a stator inductance of 46.5 mH, which adds to better electromagnetic performance and sinusoidal torque delivery. This motor has a rated voltage constant of 89.8 V/1000 rpm to provide a consistent voltage output as a function of rotational speed. With a stall torque of 2 Nm, this synchronous motor supplies adequate holding torque under locked rotor, advantageous for high-precision positioning applications. This motor’s encoder system is a 10 angular minute resolver that provides reliable position feedback even during changing loads.
