Mitsubishi HG-Series Common Features

Optimal Temperature:

The Mitsubishi HG Series typically operates between 0 degrees Celsius and +40 degrees Celsius (32°F and 104°F). This range is selected to guarantee that the motors can function well in most industrial settings, which frequently have temperature variations due to cooling systems, climate, and machine heat production. The HG-MR43K, HG-KR73B, and HG-SR102K modules all function within the same temperature range.

Operating Voltage:

The Mitsubishi HG Series’ operating voltage is normally 200 volts AC. Since this voltage range is commonly found in industrial settings, these motors may be employed in a variety of sectors. This typical alternating current voltage was selected as a compromise between supplying sufficient power for high-performance activities and preserving interoperability with conventional industrial electrical systems. The majority of modules, including HG-JR534K, HG-KR13B, HG-SR102BK, and HG-KR73K, function with this standard operating voltage.

Rated Speed:

The best speed at which the Mitsubishi HG Series motors can reliably and effectively produce the specified performance is known as the “rated speed.” The average speed of the Mitsubishi HG Series varies; however, most motors operate at this speed. This range typically revolves around 3000 (RPM), which is a benchmark speed that strikes a compromise between motor lifetime, torque, and efficiency. For instance, the average rated speed of the modules HG-KR23B, HG-KR43B, HG-KR73, and HG-SR102 is 3000 (RPM).

Torque:

A key feature of servo motors is torque, which is the rotational force the motor can produce. Torque is a crucial parameter in the Mitsubishi HG Series, determining the motor’s capacity to drive a load. Typically having a nominal (or rated) torque and a maximum torque capacity, the series comprises motors with various torque values to suit different industrial applications. The maximum torque is the greatest torque a motor can create for brief periods without overheating or suffering damage. In contrast, the nominal torque is the sustained torque the motor can give continually. Within the HG Series, which includes modules such as the HG-KR13B, HG-KR053, HG-KR23J, HG-MR43K, and HG-SR102B, have the torque ranging from a minimal value of about 2.4 Nm to a highest torque of 8.4 Nm.

Protection Class:

A key feature that indicates a servo motor’s degree of protection against environmental elements like dust and moisture is its Protection Class, represented by its Ingress Protection (IP) rating. The motor’s adaptability for different industrial settings is largely determined by this rating, particularly in cases when exposure to such factors is a problem. The IP65 and IP67 protection ratings are typically the most common in the Mitsubishi HG Series. The HG-JR534K and HG-SR102 modules have an IP67 rating, whereas the HG-KR053, HG-KR13, HG-KR13B, and HG-MR43K modules have an IP65 rating.

Output Power Capacity:

A crucial component of servo motors is their output power capacity, which shows the highest power they can attain when used. It’s a crucial factor because it directly affects the motor’s capacity to drive a load, particularly in demanding industrial settings. Many motors in the Mitsubishi HG Series have an output power capability in the range of 0.5Kw-0.75 kW. This capacity is a flexible option that balances performance and energy usage. It is adequate for various industrial uses, offering the necessary power for most medium-duty jobs while preserving efficiency. As an illustration, the output power capacity of the modules HG-KR053, HG-KR13, HG-KR13B, HG-MR43K, HG-JR534K, and HG-SR102 is approximately lies between 0.5Kw- 0.75 kW.
