DirectIndustry's servo-drive and servo-amplifier index lists 94 companies and 473 catalog products, with ADVANCED Motion Controls (122 listings), Copley Controls (31), and Ingenia Motion Control (36) dominating the global directory as of 2026-06-24 [S2].
Made-in-China's "Servo Drive Price 2026" catalog shows digital servo drives priced from US$100 to US$12,000 per piece at 1-piece MOQ, with 3-axis Mitsubishi-compatible units such as the MR-J4W3-444B listed at US$420.00 and Wuhan Sine Electric publishing a US$1.00-1,198.00 controller band [S7][S8].
Global Directory Tiers: Who Lists What
The DirectIndustry A-Z sweep covers ACS Motion Control, ADTECH, Allen-Bradley, AMKmotion, ANCA Motion, Applied Motion Products, AXOR INDUSTRIES, B&R, Baumüller, Beckhoff, Beijer, Bosch Rexroth, Cambridge Technology, Copley Controls, Delta Electronics, Elmo Motion Control, ESR Pollmeier, ESTUN, FESTO, GSK, Heidrive, Infranor, JAT, Jetter, KEB, KEBA, Kollmorgen, Lenze, LinMot, MITSUBISHI, NIDEC, ORIENTAL MOTOR, Parker, Phase Motion Control, Schneider, SIEB & MEYER, Siemens Safety Integrated, SIGMATEK, Synapticon, Technosoft, TECO, Trio, WITTENSTEIN, YASKAWA, and Yaskawa America Drives & Motion Division [S2].
ADVANCED Motion Controls' corporate page records 35+ years of manufacturing and 14k+ part numbers for high-performance servo drives and motor controllers, positioning the US firm as the catalog volume leader [S4]. Chinese OEMs Inovance (10), ESTUN (9), SUZHOU VEICHI (9), Shenzhen INVT (3), SHANGHAI STEP (1), and Shanghai Siheng Motor (7) hold the largest Asia-side catalog footprints on the same index [S2].
Spec Bands: Current, Power, and Motor Type
Festo's CMMT-AS compact AC servo drive delivers 3-12 A at 0.4-12 kW with EtherCAT-native integration, while the CMMP-AS multi-axis platform spans 2-15 A at 0.5-9 kW and accepts expansion modules including a safety card [S3].
Control Techniques' Unidrive M700 stretches from 0.75 kW up to 2,800 kW output, the widest single-product power band in the survey and the typical choice for high-inertia lines and large servo pumps [S3]. VEICHI's SD700, SD780, and SD710 series each cover 1-120 A and 0.1-250 kW with current options of 1.8-5.5 A on SD780, giving panel builders a single-vendor three-tier current ladder for general-purpose machine tools [S3].
Across the 473-product index, 297 catalog entries are DC drives, 207 are AC, 173 are brushless, 124 are brushed, 116 are three-phase motor variants, and single-phase entries round out the lower-power servo niche [S2].
Bus Protocols, Feedback, and Safety
EtherCAT appears as the dominant on-board bus for European and US high-end units (Festo CMMP-AS, AMK, Beckhoff, KEB, Synapticon, Elmo, Ingenia, Jetter), while EtherNet/IP, PROFINET, and CANopen surface on Allen-Bradley, Schneider, Bosch Rexroth, and B&R lines indexed in the same catalog [S2][S3].
Servomotor feedback in these drives typically accepts resolver, multi-encoder, and Hiperface / EnDat inputs — the Lenze i750, for example, lists 5-64 A at 1.1-15 kW with resolver/multi-encoder input, holding-brake control, motor temperature monitoring, and a 2x digital input front end [S3]. Engineers specifying for functional safety should verify whether the chosen SKU carries a TÜV-certified STO/SS1 module; only some catalogs (Festo CMMP-AS with safety card, Beckhoff AX5000, Elmo, KEB F5) declare integrated SIL-rated STO in the listing text [S3].
Selection Criteria: Matching Supplier Tier to Application
Four decision gates cut the list quickly: (1) current/power band, (2) feedback device, (3) bus protocol compatibility with the host controller, and (4) safety certification depth. A 0.4-12 kW EtherCAT application in a packaging line is well served by Festo CMMT-AS; a 0.75-2,800 kW process line maps to Control Techniques M700; a 1-120 A general-purpose machine tool fits VEICHI SD700/710/780; and a 0.1-15 kW low-voltage DC servo with resolver feedback matches Lenze i750 [S3].
China-side volume supply concentrates in Guangdong (Inovance Shenzhen, INVT, Dingshen, Haozhi, Henneng), Wuhan (Maxsine, Sine Electric, Honpine), and Suzhou (VEICHI), where MOQs drop to 1 piece and reference designs trace back to Mitsubishi MR-J and Yaskawa Sigma-7 architectures [S7][S8][S9][S10]. For a deeper look at the related motion-control and upstream tooling side, see this harmonic reducer fit-gate checklist — pairing the right servo drive with a correctly specified strain-wave gear is what separates a 12-month mean-time-between-failure from a 3-month one.
Price and Lead-Time Reality Check
Made-in-China's 2026 price band starts at US$49.90 (Sichuan Hongju) and US$100-110 for the Ax5203-0000 digital compact servo drive (Henneng Trade), climbs to US$135-182 for entry-level general-purpose units, and reaches US$420 for the 3-axis MR-J4W3-444B clone with built-in dynamic brake and regenerative resistor [S7][S9]. On the controller side, Wuhan Sine Electric publishes a US$1.00-1,198.00 per-set band for general-purpose controllers at 1-set MOQ [S8].
Lead-time risk is highest on European safety-certified stock (Festo CMMT-AS with safety card, Beckhoff AX5000, KEB F5) and on high-current three-phase frames above 55 A where only a handful of suppliers (Bosch Rexroth, Control Techniques, ADVANCED Motion Controls) hold stock [S2][S3]. For projects in 2026 where component allocation is a concern, see this warehouse robotics sourcing-path analysis, which covers the parallel 2026 squeeze on motion-control components feeding into AMRs and ASRS builds.
Limits, Failure Modes, and Cross-Reference Cautions
A clone of a Mitsubishi MR-J4 or Yaskawa Sigma-7 fits a 1-3 kW EtherCAT/EtherNet/IP retrofit but is not a drop-in for safety-rated cells — STO/SS1, encoder channel grounding, and CE-UL documentation differ from the OEM [S7]. On the encyclopedia side, the servo drive fundamentals page maps the PWM current-loop and torque-control terminology the catalog snippets use, and the servo motor reference clarifies the resolver-vs-encoder-vs-Hiperface trade-off that drives the feedback input choice on the i750 and CMMP-AS.
Buyers should reject bare brand-equivalence claims — "Mitsubishi-compatible" on a Chinese clone is a connector-pin and protocol map, not a firmware or warranty match — and should treat the 1-piece-MOQ / US$100 price as a sample-only figure, not a project line-item [S7][S8]. Always cross-check the vendor-published current band (3 A, 12 A, 64 A, 120 A) against the application's peak torque at stall; undersizing the drive at 1.5-2x rated current headroom is the most common root cause of IGBT trip faults in field returns.
Trackable signals to watch for the rest of 2026: DirectIndustry catalog growth past the 473-product mark [S2] and Made-in-China MOQ/price changes on the 3-axis MR-J4W3-444B clone line (US$420.00 baseline) [S7].
