Product Description:
The SS252B-2003U is a synchronous motor manufactured by Danaher that is designed for applications that necessitate precise torque delivery and delicate speed control. Powered by 240 V single-phase electricity, the motor can be used in systems that need a stable shaft spin and good power efficiency.
The SS252B-2003U synchronous motor has a power output of 0.014 horsepower and can work at 60 RPM with 50 Hz input or 72 RPM with 60 Hz input. The motor needs 0.4 A of power and connects to the grid in figure A. The frame is NEMA 42C, and it weighs 8 pounds (3.6 kg). The motor can handle a maximum load inertia of 3.0 lb-in with both stiff and flexible couplings, and its minimum running torque is 250 oz-in. If the motor only has one winding, it can hold 280 oz-in of power. If it has two windings, it can hold 450 oz-in. 6.5 oz-in is a normal amount of leftover torque. At 70 V DC, each winding needs 0.35 A of power to work. The most linear force is 50 lb and the most radial force is 25 lb. To work with 240V, you need a resistor that is 500 ohms and 50 watts.
The SS252B-2003U synchronous motor has a frequency range of 50/60 Hz and can accept a single-phase power input, which makes it more compatible with common electrical systems. The motor is made to have constant torque performance, which helps with accurate motion control. It has electrical properties for each coil that help keep the power from fluctuating while it's working. Its rated voltage input, which is 500 ohms at 50 watts, matches its rated resistance, which keeps heat from spreading. The motor's torque and inertia ratings are set so that it can work steadily under coupled load situations.
Frequently Asked Questions about SS252B-2003U:
Q: Does SS252B-2003U require an external resistor always?
A: Yes, for 240V operation it needs a 500-ohm, 50-watt resistor. This helps manage voltage and dissipate excess energy.
Q: Do SS252B-2003U windings operate on DC voltage?
A: Yes, each winding operates at 70 V DC. This helps maintain consistent current flow and controlled torque output.
Q: How does SS252B-2003U handle axial load force?
A: It handles up to 50 lb axial force. This prevents structural stress during vertical or inclined mounting applications.
Q: Why does SS252B-2003U support low shaft speed?
A: Low RPM ensures better control and precision. It is suitable for applications requiring steady and accurate motion delivery.
Q: Does SS252B-2003U torque differ by winding status?
A: Yes, holding torque is 280 oz-in with one winding and 450 oz-in with two. Dual winding increases holding capacity.
