Brief Introduction

The SIMO ZDL series is a family of separately excited direct-current motors engineered for industrial drives that demand smooth, stepless speed regulation and high starting torque. Built to metric standards, the range spans fractional-kilowatt duties up to several hundred kilowatts, with 220 V as the most frequently specified armature voltage. A representative frame such as the ZDL-432 delivers its rated output at a base speed of 1500 r/min, while the same platform supplies a motor 3kw 220v variant for light-duty machinery, so designers can specify one consistent product family across an unusually wide spread of power ratings. Frames also remain dimensionally compatible with earlier designs, so existing installations can be upgraded without re-machining foundations. Every ZDL machine is built around a rigid cast-iron or fabricated-steel frame that resists vibration and torsional load. The stator carries laminated field poles with class F insulated windings, vacuum pressure impregnated to lock the coils against movement and moisture.

The armature is dynamically balanced, keyed to a high-grade steel shaft running in grease-lubricated ball or roller bearings. Protection to IP55 and cooling by totally enclosed fan ventilation (IC411) suit dusty and humid plant environments. Terminal boxes can be rotated to four positions, mounting arrangements include B3, B5 and B35, and encoders, tachogenerators and thermal sensors are available as options. Below base speed the motor delivers essentially constant torque, since flux is held constant and speed follows armature voltage. Above base speed, field weakening extends the operating range into the constant-horsepower region, typically to twice base speed. Speed regulation is tight across the load curve, starting torque reaches two to two and a half times rated torque, and a short-time overload of 1.5 times rated current for sixty seconds is permitted at standard ratings. Insulation is class F with class B temperature rise, rated for continuous duty (S1) at ambient temperatures up to 40 °C. Speed holding to within one percent of the set point is achievable with suitable closed-loop control. ZDL motors pair naturally with modern thyristor or PWM drives.

Four-quadrant operation, regenerative braking and controlled acceleration ramps are all readily achieved, while analog references of 0–10 V or 4–20 mA and fieldbus interfaces such as Modbus RTU, Profibus and PROFINET connect the drive to a plant control system. Closed-loop feedback from an encoder or tachogenerator allows precise tension, position and speed holding, a decisive advantage where a motor 3kw 220v drive must follow a fast-changing reference. Because mill duty and machine duty differ sharply, the ZDL series is offered with a broad options list rather than a single fixed specification. Customers may choose separate or combined winding arrangements, forced ventilation for low-speed running, special shaft extensions and flanges, IP56 sealing for washdown areas, stainless hardware for coastal sites, and pre-fitted space heaters to prevent condensation during idle periods. Winding temperature detectors, bearing RTDs and shaft-mounted encoders are factory fitted on request, so a machine arrives ready to connect rather than needing later modification. The series is widely used in metallurgy and rolling mills, wire drawing and tube forming, plastic extruders, printing and coating lines, paper machines, mine winders, cranes and hoists, and heavy machine tools. In each case the combination of high breakaway torque, a wide constant-power range and repeatable low-speed behaviour makes direct current the economical choice.

Routine maintenance is limited to bearing greasing and brush inspection through generously sized inspection covers, and the brush gear is accessible without dismantling the machine. Replacement brushes, bearings and field coils are stocked as standard service items, keeping unplanned downtime brief. Every unit is routine tested for insulation resistance, no-load current, vibration and speed before dispatch, and documented test reports, spare parts and technical support accompany each delivery. Drawings, wiring diagrams and commissioning guidance are supplied with every order. From a compact motor 3kw 220v frame to the largest mill-duty machine, the SIMO ZDL series offers a coherent, well-proven answer to adjustable-speed drive requirements.
