Brief Introduction

When engineers evaluate drive options for demanding industrial environments, the discussion often begins with a 220v three phase motor, yet many applications still demand the precise speed control and high starting torque that only a well-built DC machine can deliver. The SIMQ Z2 Series DC motor, manufactured by Xi'an SIMO Motor Co., Ltd., is exactly that machine. Model Z2-71 THF1, the representative unit of this series, produces a continuous 17 kW output at 220 V and 90 A, turning at a stable 1500 r/min under S1 duty. Enclosed in a robust grey cast-iron frame with CE certification, this motor combines decades of proven Z2-series design with modern manufacturing quality, making it a dependable choice for mills, machine tools, and process lines that cannot tolerate drive inconsistency.

At the heart of the Z2-71 THF1 is a shunt (SEHUNT) excitation system, which provides the flat, predictable speed-torque characteristic that DC technology is famous for. Shunt excitation keeps rotational speed nearly constant as load changes, while remaining fully compatible with external speed regulation equipment such as thyristor converters and DC drives. This makes the motor ideal for applications requiring fine adjustment across the operating range. The nameplate specifies a thermal classification of 155 (Class F insulation), giving the winding a generous thermal margin above its standard operating temperature and extending insulation life even during heavy cyclic loading.

Mechanical and environmental design further reinforce the motor's industrial credentials. Protection is rated IP23, shielding live and rotating parts against finger contact and falling debris while allowing ample ventilation for the IC01 cooling circuit. The IM B3 foot-mounted arrangement suits standard bench, bedplate, and pedestal installations. The motor is rated for ambient temperatures of 0–40 °C and altitudes up to 1000 m above sea level, covering the majority of factory conditions worldwide. Bearings are equally conservative: a 6310/C3 deep-groove ball bearing at the drive end and a 6309/C3 at the non-drive end, both with increased internal clearance for thermal expansion and long, quiet service. The complete machine weighs 265 kg, reflecting a heavy-duty frame that resists vibration and maintains shaft alignment over years of continuous operation.

In terms of application coverage, buyers who initially shortlist a 220v three phase motor for a 220 V shop supply frequently choose this DC alternative once they factor in the control benefits. Typical uses include metal-cutting machine tools, rolling and auxiliary mill drives, hoists and winches, printing and paper machinery, plastic extruders, and laboratory or test-bench systems where wide, smooth speed variation is essential. The 1500 r/min base speed aligns with common four-pole line speeds, simplifying integration with existing gearboxes and line shafts. Because output, voltage, and current are all conventional industrial values, replacement spares, tacho couplings, and drive electronics are readily available from stock suppliers.

Quality assurance is documented rather than claimed. The motor is manufactured to enterprise standard Q/XD.514.017, and each unit carries a unique serial number-in this example 726111011001-with a production date of November 2026, ensuring full traceability from winding to final test. Every machine passes routine inspection of winding resistance, insulation resistance, and no-load performance before shipment. The CE marking on the nameplate confirms conformity with relevant European directives, simplifying export procedures for overseas distributors and OEM customers. A QR code and laser-etched plate details protect buyers against counterfeit products.

Installation and ownership costs stay low throughout the motor's life. Terminal boxes, feet, and bearing housings are dimensioned for straightforward mounting, and the widely available C3-clearance bearings mean maintenance teams can service the motor with standard parts. The 220 V armature voltage pairs naturally with common single-phase-to-DC converter supplies in smaller plants, while larger facilities can operate it from standard DC bus systems.

For procurement teams comparing options, the decision often narrows to this: a 220v three phase motor offers simplicity on an AC network, but the SIMQ Z2-71 THF1 offers something AC machines still struggle to match-precise, stable, and economical speed regulation backed by a certified Chinese manufacturer with decades of DC motor experience. Backed by Xi'an SIMO Motor Co., Ltd. and its national service hotline (400-029-1177), this 17 kW Z2-series machine is a safe, well-supported investment for any plant that values control, durability, and proven performance in one package.
