Z4 DC motor selection guide
- By speed control: constant-torque armature voltage control (down to 20 rpm), constant-power field weakening (up to 1.0-3.0x rated speed).
- By load: cranes, rolling mills, hoists and other heavy constant-torque drives; especially for high heat and wide speed range.
- By voltage: standard 160V / 400V / 440V; custom voltage available.
- By mounting: horizontal foot (IMB3) and others on request.

Z4 DC motor maintenance tips
- Brush check: replace worn brushes and keep the commutator surface clean.
- Commutator care: clean periodically to avoid excessive sparking.
- Bearing lubrication: relubricate per duty cycle; check vibration and temperature rise.
- Cooling system: forced ventilation with air filter; clean the filter for proper airflow.
Z4 DC motor FAQs
Can Z4 replace an older Z-series DC motor?
Yes. Z4 is the fourth-generation design with interchangeable frame and mounting dimensions; just verify voltage, speed and excitation (separately excited).
Does Z4 need a VFD?
No. A DC motor is speed-controlled by armature voltage or field weakening - constant torque down to 20 rpm, constant power up to 1.0-3.0x rated speed.
Are you a manufacturer of Z4 DC motors?
Yes. Jiangsu Wangpai Motor Manufacturing Co., Ltd. is a major manufacturer of Z4 series DC motors, 12,000 units per year, 13 center heights, exported worldwide, custom-built to customer standards.
Can you build to the customer's national standard?
Yes. Different countries have different standards; we supply products meeting the customer's local standard. Welcome to inquire.
