Product Description:
Pacific Scientific manufactures the BA3628-7012-48C. Since the motor’s magnetic field is created by permanent magnets, not electromagnets, it’s a permanent magnet DC motor. Removing the need for field windings and simplifying the motor design reduces the energy losses associated with field excitation. Permanent magnets make motors more efficient and compact, which is important in industrial automation, where energy and space efficiency are key. The motor housing is sealed to keep out dust, moisture and other contaminants as indicated by the “TENV” enclosure or Totally Enclosed Non-Ventilated. Since this type of enclosure uses the motor’s surface area to dissipate heat, it can be used in applications where forced air cooling is not desired or not possible. The surface area of the motor’s casing and the thermal conductivity of the materials used have a direct impact on how well this heat dissipation works. A standard specification known as the NEMA 56C defines the motor’s mounting dimensions, shaft size and other physical attributes.
Interchangeability is guaranteed by this standard, which also makes it easier to integrate into other industrial systems. A predictable mechanical interface with a 56C rating makes it easy to upgrade or replace equipment. The maximum torque the motor can produce continuously without overheating is 4.4 lb-in. For applications that need constant rotating force, such as controlling robotic arms or conveyor belts, this is important. Armature current and magnetic field strength are related to torque, and the motor’s continuous rating is its thermal limit. The maximum current the motor can handle continuously is shown by its rated current of 1.01 amps. This is directly related to the motor’s winding resistance and thermal capacity. If this current is exceeded, the motor may be damaged and generate excessive heat.
The motor’s torque output is related to the applied current by the torque constant of 0.38 lb-in/a. By adjusting the current, this constant allows for precise torque control, which is important in precision control applications. Along with voltage, the rated speed of 10.13 is a constant that defines the motor’s speed. The motor’s resistance to change in rotational speed is measured by its 21 lb-in of inertia. The motor’s physical dimensions of 19.5 inches long and 18 pounds are important for integration and installation. The motor’s footprint and space requirements inside the equipment are determined by these dimensions. The small size allows it to be used in many applications with limited space. The total inertia of the system and mechanical stress on the supporting structure are directly affected by the weight of the motor. The motor’s power output is rated 1/2 HP. This is important to ensure proper performance under load by adjusting the motor’s power to the application’s needs.
