Overview
This frame sits in the mid-power section of the Z4 family, balancing output capability, installation flexibility, and retrofit compatibility for continuous industrial operation.
In the Z4 catalogue, this frame is usually selected when users need a practical balance between electrical output and installation envelope for continuous industrial duty.
Common Models in This Frame

Typical Specifications
- Voltage: Typical armature voltage in sample rows: 400 V; series-level options include 160 V/440 V with other derived voltages on request.
- Speed: 900 to 2710 r/min (typical range from sample data).
- Power range: 40.5 to 119.0 kW (typical range from sample data).
- Cooling options: Base methods are IC06 / IC17 / IC37; blower location for this frame is typically on the drive side.
- Mounting form: IMB3/IMB35/IMV1/IMV15 in the Z4 catalogue scope.
- Efficiency: Rated-point efficiency values are listed model-by-model in the technical table; actual values depend on specific model, speed, and duty.
Installation and Dimensions
Z4 frame motors follow series-level installation platforms, with dimensions largely aligned to IEC72 practice except for the axial distance “B” between the two foot holes.
For this frame, code “1/2” in model designation indicates short/long endshield variants. Detailed dimensions vary by specific model and mounting form.
Compared with adjacent frames, Z4-200 keeps the same design language but differs in shaft, cooling demand, and installation footprint corresponding to output level.
Applications
- Heavier machine-tool and process transmission
- Rolling line auxiliary applications
- Cement and extrusion duty with steady torque demand
Compared with small frames, this frame provides higher torque and broader power combinations; compared with large frames, it keeps a more compact installation envelope.
Optional Configurations
- Compensating winding is generally not the standard configuration for this frame; confirm case-by-case if needed.
- ZYS-A tachogenerator can be installed on the non-drive side when speed feedback is required.
- Terminal box default position is right side (viewed from drive end); left side or top position is available by request.
- Special mounting and accessory combinations can be arranged for retrofit projects.
- IC05 separately ventilated variant (blower at non-drive side)
- IC666 totally enclosed air-air heat exchanger variant
- IC86W totally enclosed air-water heat exchanger variant

FAQ
What is the difference between Z4-200 and nearby frame sizes?
The main differences are power capability, speed combinations, installation footprint, and cooling demand. Final selection should be based on rated torque, base speed, and space constraints.
Can Z4-200 be configured with different cooling and mounting options?
Yes. Standard Z4 cooling includes IC06/IC17/IC37, and additional cooling structures may be available depending on frame range and project requirements. Mounting options are selected according to the catalogue scope for this frame.
Are all models in this frame interchangeable one-to-one?
Not directly. Even inside the same frame, armature core length, endshield version, speed class, and optional accessories can differ. Confirm mechanical and electrical details before replacement or retrofit.
