    • Inline Gearmotors

    Integrated motor+gearbox systems offering compact, efficient speed reduction.

    Inline gearmotors are integrated drive units in which an electric motor and a coaxial (in-line) reduction gearbox share a common axis, with the motor pinion driving the first gear stage directly. Because input and output shafts are collinear, they deliver torque multiplication and speed reduction in a straight, space-efficient package, eliminating the separate motor coupling and adapter needed for a discrete reducer-plus-motor build.

    The reduction element is most often helical (occasionally planetary or helical-worm), giving high efficiency — commonly around 96% for two stages and 94% for three stages. Catalogue ratios typically span roughly 5:1 to 100:1 per unit, with extended multi-stage builds reaching several hundred to one; output torque ranges from a few Nm to roughly 18,000 Nm, and integral motor power from about 0.12 kW to 160 kW. The integral motor is built to IEC 60034 (or NEMA), with efficiency classes IE3 (premium) and increasingly IE4 (super-premium) per IEC 60034-30-1. Gear rating follows AGMA 2001/2101 or ISO 6336 with quality per ISO 1328.

    Gears are case-hardened alloy steel (20MnCr5 / 18CrNiMo7-6), ground for quiet, efficient mesh, in cast-iron or aluminium housings on rolling bearings with reinforced seals; surface treatment and IP55/IP65 ingress protection are available.

    Configuration includes solid or hollow output shafts and flange (B5/B14) or foot mounting, foot-, flange- and shaft-mount positions, brake motors, forced or convection cooling, and inverter-duty windings; lubrication is mineral or synthetic PAO (ISO VG 220/320), frequently lifetime-filled on smaller frames. Service factor is selected per AGMA guidance.

    Himalay's MSME partners manufacture inline gearmotors with gear-rating to AGMA / ISO 6336, integral motors to IEC 60034, ISO 9001 quality systems, load and efficiency test reports and traceability; CE (Machinery Directive, plus EMC/LVD for the motor), ATEX/IECEx for hazardous areas, and SABER (Saudi Arabia) coordinated as part of the standard order flow.

    Frequently Asked Questions

    When does an inline gearmotor make more sense than a separate motor and reducer?
    As a rule of thumb, an integrated inline gearmotor suits coaxial layouts where compactness, a clean torque path and fewer alignment points matter — typically with high helical efficiency (around 94-96%) and ratios up to roughly 100:1. A separate motor plus reducer can be preferable where you need to standardise on a specific motor brand, swap motors in the field, or reuse existing motor inventory. The trade-off is integration and footprint versus modularity — share your duty and we can help weigh it.
    What's the typical MOQ for inline gearmotors?
    It varies with frame size and ratio. Small standard catalogue gearmotors usually carry higher MOQs, often in the 25-100 piece range per configuration, while larger industrial frames can start as low as 5-20 pieces. Consolidating mixed sizes under one spec package generally allows smaller quantities per line. Treat these as indicative pending a partner match to your specification.
    Which certifications and test reports are available?
    Where specified, partners can supply units under ISO 9001 with gear-rating to AGMA / ISO 6336 and integral motors built to IEC 60034, accompanied by efficiency (IE-class), load and running test reports and traceability. CE marking covering the Machinery Directive plus EMC and Low-Voltage Directive for the motor can be coordinated for EU shipments, and ATEX/IECEx execution arranged for hazardous areas. Scope is confirmed at inquiry stage.
    What motor frame, IE-class, voltage and mounting options can be specified?
    Integral motors are typically built to IEC frame sizes (with NEMA available) in efficiency class IE3 as standard and IE4 where required, for common voltages such as 230/400 V and 400/690 V at 50 Hz (60 Hz windings available), three-phase or single-phase on small frames. Mounting follows IEC 60072 conventions — B5 or B14 flange, foot, or shaft-mounted — with IP55/IP65 protection, optional brake, forced-cooling fan and inverter-duty insulation. Share your supply voltage and mounting and a partner is matched accordingly.
    Can you support OEM approvals and customisation?
    A subset of Himalay's partner network supplies gearmotors to OEMs in material handling, conveying, packaging and EV-adjacent sectors, and can configure brake motors, special ratios, encoders and hollow-shaft outputs. Share your spec or drawing at inquiry stage and we match a qualified partner; supplier audits can be arranged on a development track where needed.
    What lead time should I plan for?
    Standard catalogue gearmotors typically take around 4-8 weeks to build, test and pack; larger or inverter-duty/brake-motor configurations commonly run 8-14 weeks. Full CIF to Rotterdam, Antwerp, Jebel Ali or Dammam is generally 8-12 weeks door-to-door for standard product and 14-20 weeks for engineered specials, subject to confirmation.
