Product Description

Pacific Scientific manufactures the RMC-600 4047126. As a permanent magnet DC motor, the RMC-600 4047126 produces a magnetic field using permanent magnets instead of field coils. This design naturally gives better responsiveness and economy, which is important for applications that require accurate torque and speed control. The motor speed is 1750 RPM. Matching the motor to the driven equipment depends on this speed rating, which is the rotational velocity under normal operating conditions. Applications that require accuracy, such as automated manufacturing lines or robotic systems, rely on the steady speed control this grade offers. With the option of Totally Enclosed Non-Ventilated (TENV), the motor housing is a Totally Enclosed Fan Cooled (TEFC) design. To improve heat dissipation and allow operation in high-temperature conditions, the TEFC design uses an external fan to blow air over the motor housing.

Conversely, the TENV option uses natural convection to cool, which makes it suitable for applications where forced air circulation is not possible or not allowed. To ensure reliability in harsh industrial environments, both enclosures protect the motor from dust, dirt and moisture. The motor can tolerate working temperatures up to 180°C due to its Class H insulation grade. For continuous duty applications with high heat build up this high thermal endurance is important to minimize insulation degradation and extend the motor life. The continuous current rating of the RMC-600 4047126 is about 5.1 A. The steady-state current the motor can withstand without overheating is represented by this figure, which is important for choosing the right wiring and power source. Also, the peak current is around 54 A, which is the maximum current the motor can handle for short periods of time, such as starting or sudden load changes. About 18 lb-in is the continuous torque, which is the amount of rotating force the motor can deliver.

Torque control is one of the keys to accuracy, and the torque constant is about 4 lb-in/A, which is the ratio of the motor torque output to the input current. The motor inductance is 5.8 mH, and the resistance is 1.3 Ω, which affects the motor's electrical response time and efficiency. The motor acceleration and deceleration characteristics are affected by the rotor inertia, which is 5.2 lb-in. This is important for dynamic applications. The motor mounting and physical dimensions are NEMA 56C standard so it will fit with many industrial equipment. By meeting strict safety and performance requirements the CSA certification gives an extra layer of quality assurance.
