Technical Overview
The Z4-160-21 occupies the Frame 160 position within the Z4 Series. The table shows 2 standard reference ratings for Z4-160-21. Standard reference output covers 16.5–18.5 kW. Standard reference base speed covers 900–1000 r/min. Multiple reference ratings exist because output, base speed and armature voltage form different operating-point combinations within the model selection. They should be treated as selectable reference configurations rather than a fixed single specification or an unrestricted capability range. Cooling and mounting affect thermal performance and mechanical integration, while armature and field supplies must be checked against the drive system. Series-level technical information is used only to explain the wider Z4 design context and is not presented as a unique feature of this model. Final selection requires confirmation of the complete rating, permissible speed range, load duty, site environment, shaft interface and dimensional drawing.
Typical Applications
Compact controlled machinery
For this smaller frame and power range, suitable projects may include compact controlled machinery when rating, duty, cooling and installation are confirmed.
Rolling Mill Auxiliary Equipment
Z4 Series DC motors in this frame and power range may be considered for rolling-mill auxiliary equipment when the required operating point, duty and installation are confirmed.
Paper and Printing Machinery
Z4 Series DC motors are commonly considered for controlled drives in paper and printing machinery; suitability for this frame requires confirmation of power, speed range, cooling and duty.
Retrofit & Replacement Projects
Existing DC motor replacement projects require electrical and mechanical verification, including power, speed, armature and field voltage, shaft, mounting, centre height, overall dimensions, cooling, duty and load characteristics. Contact us for engineering review.
How to Select a Z4-160-21 DC Motor
Output and Speed
First compare the required operating point with the listed standard reference ratings. If no reference rating matches the required output or speed, provide the operating requirements for engineering evaluation. Confirm maximum speed and torque range separately.
Armature Voltage
If one of the listed armature-voltage configurations matches the drive system, it can be used as a reference selection. If a different armature voltage is required, provide the required voltage and operating point for engineering evaluation.
Field / Excitation
Confirm field voltage and excitation requirements from the selected rating and control system.
Cooling, Mounting and Duty
Verify cooling air, ambient conditions, mounting arrangement, enclosure and duty against the installation.
Replacement Projects
For a replacement, provide the original nameplate, rated power and speed, armature and field voltage, shaft dimensions, mounting, centre height, overall dimensions, cooling, duty and load characteristics.
Z4-160-21 Dimensions & Mounting Drawing
Mounting and outline dimensions depend on the final selected configuration. Request the applicable Z4-160-21 drawing for the selected rating and mounting arrangement before ordering.
Z4-160-21 Datasheet
A project-specific technical datasheet can be prepared after power, voltage, speed, cooling and mounting requirements are confirmed.
