Product Description:
The SS250B can accommodate both 50 Hz and 60 Hz frequency standards, and it operates on 120 volts as a single-phase synchronous motor. This motor was made by Danaher. Use it for tasks that require low horsepower and a constant rotational speed. When it comes to industrial automation systems, motors are a common tool for controlling the movement of items.
The power consumption and horsepower produced by the SS250B synchronous motor are 0.6 A and 0.015 HP, respectively. Both the 60 Hz and 72 Hz shaft speeds are 60 RPM. This motor has Connection Diagram A and is in the NEMA 42C size category. Pound for pound, it's 3.6 kg. Turning on both windings increases the holding torque to 450 oz-in from 250 oz-in at startup. A holding torque of 280 oz-in is produced by activating just one winding. The maximum load inertia is 3.0 lb-in regardless of whether the motor is fastened tightly or with a flexible connection. Power requirements for the motor's windings are 32 V DC and 0.7 A, respectively. A 150-ohm 50-watt resistor is required for 120 V for it to function. As a result of these characteristics, efficiency and torque remain stable even when power is scarce.
The SS250B synchronous motor can handle up to 50 lb of axial force and 25 lb of rotational force. With these values, the motor can keep its alignment and torque stability when it is directly coupled. Motion control systems need clear load limits and static torque available, and this product fits right in. It can be used in situations where the changes in shaft force must be controlled correctly. When used in motor-driven applications, the motor has consistent electrical and mechanical factors that meet the load and resistance profiles.
Frequently Asked Questions about SS250B:
Q: Why does SS250B support both frequency standards?
A: It supports 50/60 Hz to ensure compatibility with global power systems. This allows flexible integration across different regional electrical standards.
Q: Does SS250B have consistent torque across frequencies?
A: Yes, running torque and holding torque are stable across both 50 Hz and 60 Hz. This maintains consistent motor performance under varying frequencies.
Q: Why does SS250B require a series resistor?
A: The 150-ohm, 50-watt resistor ensures proper voltage regulation at 120 V. It protects the windings from electrical surges during operation.
Q: Do the axial and radial limits affect alignment?
A: Yes, 25 lb radial and 50 lb axial force ratings maintain shaft alignment. These limits protect internal components from mechanical stress.
Q: How does SS250B handle load inertia changes?
A: It supports up to 3.0 lb-in load inertia with or without flexible coupling. This ensures consistent performance under various mechanical loads.
