Neri Motori was established in 1946 by Walter Neri in San Giovanni in Persiceto, evolving from a small workshop into a prominent electric motor company. By 1968, it moved to a larger factory, and in 1989, expanded into European and international markets. A new factory opened in 1996, marking industrial growth. From 1997 to 2002, production and turnover increased significantly, establishing Neri Motori as a key player in the market. Between 2002 and 2014, the company experienced substantial growth through investments in resources, research, and technology. In 2016, a new hub was launched, doubling the company's space and enhancing logistics and production strategies.
Located in Italy's "Motor Valley," Neri Motori specializes in asynchronous electric motors, blending artisanal craftsmanship with industrial development. The company invests in technology and training to deliver advanced solutions globally, maintaining a strategic distribution network with a focus on ethical progress and environmental respect.
Neri Motori emphasizes quality, achieving certifications like ISO 9001:2015, and complies with European directives for machinery, low voltage, and electromagnetic compatibility, ensuring safety and environmental respect, which supports its competitive edge in international markets.
General Specifications: Neri Motori offers dynamically balanced rotors, a variety of voltages, and motor versions (B3, B5, B14). The motors feature IP 55 protection, S1/Class F insulation, and are designed for inverter use. They include removable feet, aluminum or cast iron frames, and high efficiency in MR IE2 and MR IE3 series.
Technical Specifications: The motors comply with international standards like IEC 60034-1 for electrical specifications and IEC 60034-5 for protection class, ensuring compatibility and efficiency.
Mechanical and Electrical Specifications: Designed for durability and performance, the motors offer options for special bearings and additional protective components, painted in specific RAL colors for different sizes.
The motors are built and tested according to IEC standards and European Directives, featuring die-cast squirrel-cage rotors, wound stators, and forced ventilation as per IEC 34-6 (IC 411). Standard power supply voltages are 230V/400V/50Hz for three-phase models, with permissible voltage variations. They comply with IEC 34-1 and EN 60034-1 for electrical and mechanical specifications, with IP 55 protection and class F insulation.
Rotors are made from die-cast aluminum or Silumin alloy. Motor shafts and tangs comply with IEC 72-1, made from C43/C40 steel. Flanges and shields are standardized according to IEC 72-1, with cast iron flanges for sizes 160-355. Ventilation is achieved through a two-way rotary fan, with options for assisted forced ventilation for electronic controls. Noise levels are measured according to IEC EN 60034-9, and vibration grades are available in standard Grade A or optional Grade B.
The standard protection rating is IP55, with options for enhanced protection in harsh environments. Terminal box positions can be adjusted for motors sized 56 to 132. Bearings are sealed and lubricated for life, with options for special grease for extreme temperatures. Sealing rings are standard on both shaft and fan sides, made from NBR up to size 132.
Insulating materials in the windings are of high quality, with class H insulation allowing a maximum temperature of 180°C. The motors are insulated in class F for standard temperature. Tropicalization treatments are available for high humidity environments. Rated voltages and frequencies are specified, with different zones indicating normal and heavy service conditions.
Neri Motori's motors comply with IEC EN 60034-1 standards, allowing operation at voltages different from the nominal within a range of ±10% for three-phase motors and ±5% for single-phase motors for short periods. The motors are designed to operate at 50 Hz but can be connected to 60 Hz with adjustments using multiplicative coefficients.
Detailed tables show the rated voltages and power outputs at different frequencies (50 Hz and 60 Hz). Motors wound for 50 Hz can operate at 60 Hz with the same rated voltage and power output, but with increased revolutions per minute (rpm) and rated current, and decreased starting current and torque.
Performance and power factor values are provided based on the operating load, with tables indicating efficiency and power factor at various load levels.
Key parameters such as rated power, voltage, starting torque, maximum torque, and rated torque are defined. The document includes formulas for calculating these values and explains the conditions under which the motors are designed to operate, including altitude and temperature limits.
Neri Motori's asynchronous three-phase squirrel-cage motors can be controlled by a constant V/f inverter. The document discusses torque characteristics, highlighting the importance of appropriate cooling and ventilation to prevent overheating, especially at low speeds or high torques.
The document lists specifications for different series of three-phase asynchronous motors (MR IE1, MR IE2, MR IE3), including power ratings, efficiency, and other performance metrics.
Three-phase asynchronous motors, specifically designed for variable speed, torque, and power, are highlighted for their high performance and efficiency. These motors, categorized under types MR IE1, MR IE2, and MR IE3, utilize high-quality materials to maintain low temperatures and high efficiency, even when controlled by inverters.
The document provides detailed specifications for motors with different pole configurations (2, 4, and 6 poles) and their respective performance metrics such as power (kW and HP), efficiency, power factor, and torque. For instance, a 2-pole motor with 0.75 kW power has an efficiency of 81.1% and a power factor of 0.71.
Dimensions for motors in both aluminum and cast iron are provided, categorized by mounting types B3, B5, and B14. Each category includes detailed measurements for various motor sizes, ensuring compatibility with different installation requirements.
Each motor is equipped with an identification nameplate that includes essential product information. The document explains the layout and data presented on these plates, ensuring users can accurately interpret the motor specifications.
Neri Motori offers a dedicated online portal for customers to access motor availability, order status, and download product drawings in 2D and 3D. This service aims to enhance customer care and maintain high-quality standards by understanding customer needs and expectations.
