Z4-160 DC Motor

Overview

This frame belongs to the compact end of the Z4 family, focused on easier integration, smaller footprint, and flexible retrofit space in medium-duty production lines.

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.

Manufacturer Perspective

As a professional DC motor manufacturer and industrial DC motor manufacturer, we produce compact Z4 frames for space-saving layouts, retrofit flexibility, and stable auxiliary drive operation. For small-frame projects, customers typically work with us as a practical DC motor supplier and China DC motor manufacturer when installation space is limited.

For Z4-100 to Z4-160, our Z4 DC motor manufacturer perspective focuses on compact integration, service accessibility, and consistent variable-speed performance in lighter industrial duty.

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: 16.5 to 49.5 kW (typical range from sample data).
  • Cooling options: Base methods are IC06 / IC17 / IC37; blower location for this frame is typically on the non-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, Z4-160 keeps the same design language but differs in shaft, cooling demand, and installation footprint corresponding to output level.

In project engineering, installation envelope differences between adjacent frames should be checked together with shaft arrangement, coupling interface, and terminal space.

Maintenance accessibility should be confirmed for brush inspection, terminal operation, and cooling-path service in the final equipment layout.

Applications

  • General industrial process lines
  • Medium-duty mixer and conveyor drives
  • Cement and paper machine sub-drives

Compared with larger frames, this frame prioritizes compact layout and easier machine integration over maximum power density.

This frame size is typically chosen where compact motor layout and stable DC drive performance are required, especially when installation space is limited but process continuity is still critical.

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.
  • IC410 totally enclosed frame-cooled variant
  • IC01 shaft-fan self-cooled variant
  • 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 Z4-160 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 Z4-160 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.

Is Z4-160 suitable for compact retrofit projects?

Yes. Z4-160 is typically selected when installation space is limited but stable DC speed regulation and reliable auxiliary-drive performance are still required.

Can the manufacturer customize this DC motor frame?

Yes. This frame can be customized based on project requirements, including voltage, speed, mounting arrangement, cooling method, terminal box orientation, and accessory configuration.
