The electric motor 0.37 kW HC70R 71B 4 represents a specific class of industrial power units designed for various light-duty applications. Understanding its nomenclature and specifications is crucial for selecting the right motor for your operational needs.
This comprehensive guide delves into the technical aspects, key features, and ideal applications of this versatile motor, ensuring you make informed decisions. We will explore what each part of its designation means and how it translates into practical performance.
Deciphering the 0.37 kW Power Rating
The '0.37 kW' in the motor's designation refers to its nominal power output, which is equivalent to approximately 0.5 horsepower (HP). This power rating indicates the motor's capacity to perform work under continuous operation.
Motors of this size are typically utilized in applications that require moderate power, balancing efficiency with the operational demands of smaller machinery. Their low power consumption makes them an energy-efficient choice for many industrial and commercial settings.
The Significance of HC70R and IEC 71B Frame Size
The '71B' component specifies the motor's IEC (International Electrotechnical Commission) frame size, indicating standard dimensions for mounting and shaft height. An IEC 71B frame typically features a shaft height of 71 millimeters, ensuring compatibility with standardized equipment and machinery bases.
While 'HC70R' often denotes a specific manufacturer's series or model variant, it generally implies design characteristics like compactness or a particular mounting configuration, such as B3 (foot mounted), B5 (flange mounted), or B14 (smaller flange mounted). These standardized frames facilitate easy replacement and integration into diverse systems without extensive modifications.
Understanding the 4-Pole Configuration
The '4' in the motor's full designation indicates that it is a 4-pole motor. The number of poles directly influences the motor's synchronous speed.
For a 50 Hz power supply, a 4-pole motor typically runs at a synchronous speed of 1500 RPM, while on a 60 Hz supply, it operates at 1800 RPM. This speed range is suitable for a wide array of applications that require consistent, moderate rotational velocity.
