SASH 4IK60A-BF-E10 Induction Motor – 4IK Series

SASH 4IK60A-BF-E10: 60W Flange-Mount Single-Phase Induction Motor for Industrial Drive Applications

The SASH 4IK60A-BF-E10 is a 60-watt, single-phase capacitor-run induction motor engineered for continuous-duty operation in light-to-medium industrial drive systems. Designed around the IEC 4-frame standard, this unit delivers a synchronous speed of 1,300–1,550 RPM depending on supply frequency (50 Hz or 60 Hz), with a flange (BF) mounting interface and a 10 mm output shaft diameter. Its compact torque-to-volume ratio and thermally stable winding construction make it a reliable choice for OEM machinery builders and MRO replacement sourcing across packaging, conveyor, textile, and laboratory automation sectors.

The motor operates on 110V or 220V AC single-phase supply and requires an external run capacitor — typically rated 4–6 µF at 450V AC — to establish the phase displacement necessary for self-starting torque generation. The BF flange interface conforms to standard 4-frame bolt circle geometry, enabling direct mechanical substitution in existing machine frames without adapter hardware. The E10 shaft suffix specifies a 10 mm diameter output shaft; E8 and E12 variants exist for applications requiring different coupling bores.

Insulation is rated to Class B (130°C) as standard, with Class F (155°C) available in high-ambient configurations. The IP44 enclosure rating provides protection against solid particles greater than 1 mm and splash water from any direction, making the motor suitable for indoor industrial environments with moderate contamination exposure. Rotation direction is field-reversible by swapping the capacitor connection polarity, eliminating the need for a separate reverse-wound unit in bidirectional drive applications.

For speed reduction below the base RPM range, the 4IK60A-BF-E10 is mechanically compatible with the SASH 4GN series gearheads, which offer gear ratios from 3:1 to 200:1 in both parallel-shaft and right-angle configurations. This motor-gearhead combination is a standard building block in Asian OEM machinery and is widely stocked for MRO replacement across Southeast Asia, the Middle East, and Eastern Europe.

Technical Parameters

Hardware Logical Analysis

The 4IK60A-BF-E10 operates on the capacitor-run induction principle, where a permanently connected run capacitor introduces a 90° electrical phase shift between the main winding and the auxiliary winding. This phase displacement generates a rotating magnetic field within the stator, producing starting and running torque without the need for a centrifugal switch — a mechanical component that represents a common failure mode in capacitor-start designs. The absence of a centrifugal switch improves long-term reliability in applications with frequent start-stop cycling, such as packaging feeders and indexing conveyors.

The stator lamination stack is constructed from cold-rolled silicon steel (typically 0.5 mm grade), which reduces eddy current losses and limits core temperature rise under sustained load. The rotor is a squirrel-cage type with die-cast aluminum conductors, providing low rotor resistance and stable slip characteristics across the operating speed range. Slip at rated load is typically 3–5%, yielding a no-load speed close to synchronous and a full-load speed of approximately 1,250–1,480 RPM depending on supply frequency.

The BF flange interface is machined to tight concentricity tolerances, ensuring that shaft runout remains within acceptable limits when paired with SASH 4GN gearheads. This is particularly relevant in applications where angular misalignment between the motor shaft and gearhead input would generate radial bearing loads, accelerating wear. The 10 mm shaft (E10) is ground to h6 tolerance class, compatible with standard coupling bores and gearhead input flanges without additional machining.

Thermal management relies on an external cooling fan integrated into the rotor end cap, which circulates air across the stator frame fins. At 60 W continuous output, the thermal equilibrium temperature rise above ambient (40°C rated) remains within Class B limits, providing a thermal margin of approximately 50°C before insulation degradation onset. This margin supports operation in ambient temperatures up to 40°C without derating, and up to 50°C with a 10–15% power derating applied.

EMC performance is inherent to the induction motor topology — no commutator or brush contact means no high-frequency conducted emissions from switching arcs. For installations in electrically sensitive environments, a standard line filter (e.g., 250V, 6A common-mode choke) placed upstream of the motor supply is sufficient to meet EN 61000-3-2 harmonic current limits for Class A equipment.

System Integration Benefits

• Direct PLC relay output compatibility: The motor’s single-phase DOL start characteristic allows direct switching via standard relay output modules on Siemens S7-1200/1500, Mitsubishi FX5U, Omron CP1H, and Allen-Bradley Micro820 series without intermediate motor starters for loads below 60 W.
• Bidirectional control without dual-wound motor: Reversing rotation requires only a capacitor polarity swap via a DPDT relay, reducing panel wiring complexity and BOM cost compared to separate CW/CCW motor units.
• Gearhead modularity: The 4GN gearhead series provides output speeds from 6.5 RPM to 433 RPM from a single motor frame, enabling a single SKU to serve multiple speed requirements across a product line.
• Thermal overload protection integration: The motor’s stable slip-speed characteristic allows accurate overload detection using standard bimetallic overload relays sized to the 60 W rated current, without requiring electronic motor protection units.
• Low inrush current profile: Capacitor-run topology limits starting current to approximately 2–3× rated current (versus 5–7× for DOL induction motors), reducing voltage dip on shared supply rails in multi-motor panels.
• Standardized frame geometry: IEC 4-frame compliance ensures dimensional interchangeability with equivalent-frame motors from Oriental Motor, Zhongda, and Luyang, simplifying multi-source procurement strategies for MRO operations.
• Minimal maintenance interval: Sealed ball bearings (2RS type) are factory-lubricated for the motor’s rated service life, eliminating scheduled re-greasing requirements in most industrial duty cycles.
• Soft-starter compatibility: For applications requiring reduced mechanical shock at startup (e.g., belt conveyors with high static friction), the motor is compatible with standard single-phase electronic soft starters, reducing peak torque at startup by 30–50%.

Quality Assurance & Global Logistics

Every SASH 4IK60A-BF-E10 unit supplied through siemensplc.com is sourced from verified manufacturer channels and undergoes a structured incoming inspection protocol before dispatch. Inspection procedures include nameplate data verification against purchase order specifications, insulation resistance measurement (minimum 100 MΩ at 500V DC megger test), no-load run test at rated voltage to confirm rotation direction and absence of abnormal vibration or acoustic signatures, and dimensional verification of shaft diameter and flange bolt circle.

Traceability documentation — including batch number, country of origin declaration, and inspection records — is available upon request for OEM customers and MRO operations requiring component-level audit trails. A 12-month warranty from the date of shipment covers manufacturing defects in materials and workmanship under normal operating conditions as defined by the SASH product specification.

Logistics operations are based in Xiamen, China — a major southeastern port city with direct access to international freight forwarding networks serving Europe, the Middle East, Southeast Asia, and the Americas. In-stock units are dispatched within 1–3 business days via DHL Express, FedEx International Priority, or sea freight consolidation depending on order volume and destination. Export documentation including commercial invoice, packing list, and certificate of origin is prepared as standard for all international shipments. For time-critical MRO requirements, air freight with next-flight-out options is available upon request.
