三明 List of Products and Services

The structure of Nidec's pressure-resistant explosion-proof motors takes the following into consideration: - A strong structure with increased thickness of parts compared to standard applications. - Dimensions and precision of gaps and depths at fitting parts, joints, and shaft penetration areas according to explosion ratings. - Bolts are designed with a locking structure that cannot be loosened with standard wrenches or pliers, preventing disassembly by anyone other than specialists, as opening the container would result in loss of explosion-proof performance. - The temperature rise on the surface of the container that may come into contact with explosive gases is kept below specified temperatures according to their ignition levels. The structure of Nidec's increased safety explosion-proof motors considers the following: - The temperature rise limit of the winding is kept lower than usual according to the temperature rating. - The creepage distance and insulation space distance are set to larger values than standard. - The bolts on the terminal box cover are designed with a locking structure to prevent disassembly by anyone other than specialists. - The temperature rise in areas that may come into contact with explosive gases is kept below specified temperatures according to their ignition levels. - The allowable restraint time is 7 to 10 seconds. Allowable restraint time: The time until the temperature rise, when the rotor of the motor is restrained and rated voltage at rated frequency is applied to the stator, reaches the temperature rise limit specified according to the motor's heat resistance class and temperature rating.

By using servo control, it provides high-precision feedback of position and speed information, enabling high-precision positioning and smooth operation without loss of steps. The dedicated software can be downloaded from our company website, where the latest parameters have been added, allowing you to utilize a wealth of features. Functions such as "servo tuning," "basic functions," "torque limit function," "origin return and jog," "input branching," and "normal branching" are categorized by application, allowing easy access to the necessary parameter groups. A new "auto-tuning" dedicated screen has been added to achieve time-saving tuning. The amplifier is equipped with a USB port, allowing direct connection to a computer for teaching on the computer. The programming capacity is 256 lines, enabling various motion specifications such as "acceleration/deceleration time," "waiting time," "S-curve," "loop (repetitive motion)," "M code," "torque settings," "movement amount," and "speed." * The point table function can be used when a higher-level controller is not needed. * For more details, please refer to the PDF documentation or feel free to contact us.
