Marine Variable Frequency Explosion-Proof Electric Motors Classification
1. By motor principle
They can be divided into explosion-proof asynchronous motors, explosion-proof synchronous motors, and explosion-proof DC motors, etc.
2. By usage location
Available for underground coal mine use and factory use explosion-proof motors.
3. Divided by explosion-proof principles
Available in explosion-proof motors, increased safety motors, positive pressure motors, non-sparking motors, and dust explosion-proof motors, etc.
4. By matching host units
Divided into explosion-proof motors for coal mine conveyors, coal mine winches, rock drilling machines, local coal mine fans, valve, loud explosion-proof fans, marine explosion-proof motors, lifting and metallurgical explosion-proof motors, and brushless excitation synchronous motors for hydrogenation unit accessories. Additionally, they can be categorized by technical specifications such as rated voltage, efficiency, etc., including high-voltage explosion-proof motors, high-efficiency explosion-proof motors, high-slip rate explosion-proof motors, and high-starting torque explosion-proof motors.
The main features of explosion-proof motors are as follows:
1. The power ratings, installation dimensions, and speed correspond to DIN 42673, with necessary adjustments made for compatibility with the YB series and interchangeability with the Y2 series, ensuring enhanced effectiveness and applicability.
2. Full series utilizes F-grade insulation, temperature rise evaluated according to B-grade standards.
3. Noise limits are lower than the YB series, approaching the I-grade noise of the YB series; vibration limits are comparable to the YB series.
4. Enclosure protection rating upgraded to IP55.
5. The full series features low-noise deep groove ball bearings, with motor bases having a center height of 180mm or above, equipped with oil injection and drainage devices.
6. Motor radiators come in two types: parallel horizontal distribution and radiant distribution, with parallel horizontal distribution being the primary type.
7. Key performance indicators meet international standards from the early 1990s.

The main characteristics of the marine frequency conversion explosion-proof motor are:
1. The housing boasts high-sealing properties to minimize or prevent dust from entering the housing. Should it manage to enter, the quantity is not sufficient to pose a fire ignition risk.
2. The surface of the control housing must not exceed the allowed temperature as specified in the temperature group. It has been used on mechanical equipment in national grain reserve warehouses. The national standard for dust explosion-proof electrical equipment is GB 12476.1-90 "Dust Explosion-Proof Electrical Equipment for Explosive Dust Environments."
Taizhou Yaxin Marine Electric Motor Manufacturing Co., Ltd. has passed the ISO9001:2000 international quality system certification, and the total production and sales volume of electric motors has been increasing year by year.
