AC (Alternating Current) motors are electric motors that operate on alternating current, converting electrical energy into mechanical energy to perform various tasks. Widely used in industrial, commercial, and residential applications, AC motors are known for their efficiency, reliability, and versatility. AC Motor devideds into few types of motor, Industion Motor, Speed Control Motor, Reversible Motor, Reversible Brake Motor, Reversible Brake Control Motor. Each of these types of AC motors serves specific purposes and can be selected based on the requirements of the application. For example, a reversible motor might be used in conveyor systems where the direction of movement needs to be changed periodically, while a speed control motor could be employed in applications where variable speeds are essential. The choice depends on the particular needs of the system or process being powered by the motor.
Meister induction motors are a series of miniature AC induction motors from Woojin, a South Korean company. They fully comply with JIS IK standards, are compatible with the Malaysian 220V/50Hz power grid, and feature four main functions: constant speed, reversibility, braking, and speed regulation. They can directly replace mainstream brands such as Dongfang Motor and Dongli.

iMS able to convert all below brand name to home brand model for your convenince. 1)Oriental Motor: The IK/KIIS series is the benchmark for JIS small induction motors, available in single-phase and three-phase versions (such as 4IK25GN-C, 7IK200VJS), widely used in automated production lines.
2)Panasonic (formerly National): M91X/M91Z series, JIS size compatible, suitable for small equipment and conveyors.
3)NIDEC / Nissei
4)LG Innotek / SPG / LIMA / EXCEL : AC Mini series, JIS size compatible, low noise, used in home appliances and industrial automation
5)GGM: K7IG series (e.g., K7IG15NJ), JIS IK type interface, can directly replace Japanese brands, more affordable
6)TL/TUNG LEE: 4TNIK/IK series (e.g., 4TNIK25GN-C, 2IK6GN-C), fully JIS size compatible, high cost performance, common in Southeast Asian markets
7)TECO: AEVF/AM series, JIS standard design, compatible with gearboxes, suitable for factory automation
8)LIMING: IK type induction motor, JIS mounting dimensions, often matched with the same brand of reducer
9)STS: 15w3ik15gn-c and other models, JIS IK standard, used in packaging machinery and conveyor lines
10)VTV: IK series (such as 90w mini IK motor), JIS size compatible, significant price advantage, suitable for batch equipment
11)LDS Small Induction Motor
12)ZD Motor: IK/4IK series, manufactured according to JIS standards, can directly replace imports, commonly used in domestic factory automation
13)WOLONG Electric: SM series, meets JIS efficiency standards, complete global certifications, suitable for export equipment
14)Dayang Motor: Mini-AC series, JIS Flange and shaft diameter, compatible with reducers, for use in automotive parts production lines.
Supplementary Notes: JIS Compatibility: The core is the installation dimensions (flange, shaft diameter, center height), voltage/frequency (100V/200V, 50/60Hz), and wiring method conforming to JIS C 4212/C 4034 standards; the IK type (e.g., 4IK25GN-C) is a universal interface for small Japanese induction motors, and many alternative brands from Taiwan/Mainland China/Korea use the same interface.
Price Gradient: Japanese original > Korean brands > Taiwanese brands > Mainland China brands; if direct replacement and cost control are desired, prioritize Taiwanese brands like Dongli and Chenggang, or Mainland China brands like Weitewei and Wolong.
Selection Points: Confirm power, voltage, number of phases, shaft diameter, flange size, whether it includes a brake/reducer, and verify the JIS standard number to avoid installation incompatibility.
