Product Description:
The ST3640-3445-48HC Permanent Magnet DC Motor is manufactured by Pacific Scientific for precision and long-term reliability in controlled environments. This motor operates on a 115 V DC power supply and consumes a rated current of 4.5 A during operations. With a power output of 1/2 HP, this motor provides reliable mechanical performance across different industrial and automation applications.
With constant torque at rated load conditions, this motor provides a stable rotational speed of 1800 RPM, which is ideal for use in systems needing effective speed control and a reliable power supply. This motor also includes a permanent magnet (PM) field type to make it compact and energy-efficient. In this motor, the availability of permanent magnets eliminates the need for separate field windings for smoother and more efficient operations. This motor’s TENV (Totally Enclosed Non-Ventilated) enclosure is specifically designed to avoid external contaminations, such as dust and debris. The 1.4 Form Factor (FF) in this motor ensures standard DC motor drive compatibility to operate at peak performance without overloading the motor or control system. With an ambient temperature of -15°C to +25°C, the ST3640-3445-48HC motor provides stable operation under low and moderate temperature conditions.
The durability of this motor is enhanced by utilizing large sealed bearings. These bearings are designed to lower friction and prolong the operations of this motor with less maintenance. The rugged fused commutator improves mechanical strength and minimizes commutator-type failures under heavy-load or extended-use conditions. This motor is structurally designed with versatile installation options and accommodates both NEMA and Metric mounting arrangements to make easy integration into existing systems. The ST3640-3445-48HC motor also comes with Class H insulation to provide high thermal resistance for high-duty cycles.
Frequently Asked Questions about ST3640-3445-48HC:
Q: How does the fused commutator benefit the ST3640-3445-48HC motor?
A: It enhances durability under extended use and reduces mechanical wear over time. This is ideal for applications requiring stable electrical performance.
Q: Why is Class H insulation used in this motor?
A: Class H insulation allows the motor to handle higher thermal stress. This makes it more reliable in continuous duty applications.
Q: How does the 1.4 form factor impact system compatibility?
A: It ensures compatibility with standard DC motor drives. This allows precise current control and stable motor operation.
Q: What is the advantage of using sealed bearings in this model?
A: Sealed bearings reduce the need for lubrication and prevent contamination. This increases motor longevity with lower maintenance.
Q: How does operating at 1800 RPM benefit automation applications?
A: It ensures uniform speed control under load. This is crucial for synchronized operations and timing-based systems.
