Meister Reversible Brake Motors are the core micro AC motor product line of the MEISTER brand under Woojin Servo System in South Korea. They feature instantaneous forward and reverse rotation with power-off braking, are compatible with JIS small motor standards, and are widely used in automated production lines, conveyors, packaging, and other scenarios requiring frequent reversing. Below are complete model numbers, specifications, selection information, and local information for Malaysia.
I. Brand and Positioning
Brand Relationship: Woojin = MEISTER (Woojin Servo System's own brand, established in 1994, specializing in miniature AC motors/gearboxes, 90% exported to Japan and Europe, ISO9001, UL, CE certified)
Core Functions: Reversible + Electromagnetic Brake
Instantaneous forward/reverse switching, rated continuous operation for 30 minutes (frequent reversing conditions)
Immediate braking upon power failure, braking torque approximately 10% of rated torque, anti-rollover, accurate positioning
Compatibility Standard: JIS small motor size (IK type), can directly replace Japanese models of the same power from Dongfang Motor, Panasonic, etc.
II. Complete Model Series (Sold in Malaysia)

25W RHK8PO25-2C 220V 50/60Hz 80mm Electromagnetic Brake
40W RHK9PF40-2C 220V 50/60Hz 90mm Electromagnetic Brake
90W RHK9PG90-2C 220V 50/60Hz 90mm Electromagnetic Brake
2. Reversible Brake Speed-Regulating Motor (RHKT Series, with Speed Regulation)
RHKT6PF6-2CGS: 6W Reversible Brake + Speed Regulation (with HC Series Speed Regulator)
3. Pure Reversible Motor (RH) (Series, without brakes, for comparison reference)
RH6PF6-22 (6W), RH7PF15-2C (15W), RH8PO25-2C (25W), RH9PG60-2C (60W)
III. Key Technical Parameters (General)
Voltage: Single-phase 220V (50/60Hz, Malaysian standard)
Insulation Class: Class B / Class F
Protection Class: IP20 (Standard)
Braking Method: Power-off electromagnetic brake (DC 24V built-in rectifier)
Continuous Operation: 30 minutes rated (frequent forward and reverse rotation generates significant heat, unsuitable for long-term continuous operation)
Speed: 50Hz ~1300–1400rpm; 60Hz ~1550–1700rpm
Suitable Reduction Ratio: 3:1 ~ 180:1 (same brand PF/PO/PG gearbox)
IV. Selection Considerations (Malaysian Operating Conditions)
Power Matching: Select according to load 6W/15W/25W/40W/90W, RHK brake motors preferred (positioning/anti-slip)
Gearbox: Same brand PF/PO/PG series, direct matching, no adapter required
Speed adjustment requirements: For speed adjustment, select RHKT + HC speed controller (e.g., HC40I-22G)
Installation: JIS IK flange/shaft diameter, direct replacement for Oriental Motor 4IK, Panasonic M91X, etc.
Working conditions: Suitable for frequent forward and reverse rotation + positioning and stopping (conveyor, sorting, packaging, valves)

VI. Comparison with Japanese/Taiwanese Brands (Malaysian Market)
Table: Brand Type Price Delivery Compatibility Applicable Scenarios
Woojin/MEISTER Reversible Brake Low to Medium Malaysia Stock JIS Fully Compliant Automated Production Lines, Frequent Reversing
Dongfang Motor Reversible Brake High Imported JIS Standard Precision Equipment
Dongli (Taiwan) Reversible Brake Low Local JIS Compliant Economical Equipment
VII. Selection Recommendations (Malaysian Factory)
Preferred RHK Series: Reversible + Brake in One Step, Suitable for Automation Upgrades in Malaysian Factories
Power Recommendation: Small Conveyor/Packaging → 15W–25W; Medium Production Line → 40W–90W
Supporting components: Same brand gearbox + speed controller, best compatibility, reduces adjustment
Procurement: Contact IMS Johor Bahru, in-stock + local after-sales service, more cost-effective than imported Japanese products
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.
