Nidec Explosion-Proof Quick Brake Motor: High Performance and High Safety.
Explosion-proof quick brake motor with a built-in braking mechanism, incorporating heat-resistant classes E and B in a rational manner.
● Simple structure without a power amplification device The operating electromagnet is a short-stroke type of three-phase AC, and the movable iron core directly applies braking force to the brake disc, resulting in a simple structure. ● Easy inspection and adjustment of the brake section Internal inspection and brake pad adjustment can be done simply by removing the brake cover. ● Compatible with Class 1 hazardous locations (Zone 1) Can be used in locations where explosive atmospheres are likely to be generated under normal conditions. ● High reliability with no brake pad chattering The brake disc is suspended by a flow and spring, preventing sliding except during braking, which eliminates abnormal heating or wear due to chattering motion, regardless of whether the motor is mounted horizontally or vertically. ● Low impact force and safe A unique cushioning device is provided to absorb the kinetic energy of the movable element when the operating electromagnet is energized, resulting in low impact force. ● Usable until the brake lining reaches 1mm The brake lining is made from a material with a high wear coefficient and an extremely low wear rate, allowing a thickness of 3mm to be used until it reaches 1mm, eliminating the need for frequent lining replacements. ● Ignition degree G4, applicable in most hazardous atmospheres, explosion grade d2 Sangmei Co., Ltd. is an authorized distributor (trading company) of Nidec Techno Motor Co., Ltd.
basic information
The structure of the pressure-resistant explosion-proof motor considers the following aspects: - A strong structure with increased thickness of components compared to normal applications. - The gaps and depths at fitting parts, joints, and shaft penetration areas are dimensioned and precise according to the explosion grade. - The 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 a 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 the temperature determined according to their ignition point.
