Brief Introduction

As an upgraded high-power variant in Xi'an AIMIN's Z4 DC Current motor lineup, the Z4-250-21 is engineered to tackle more demanding heavy-load applications (vs. the Z4-250-12). Boasting 185kW rated power, 440V voltage, and a 1500/2200 rpm wide speed range, it's built to deliver sustained, high-torque output for large-scale industrial equipment.

Key Advantages & Distinctive Features (vs. Lower-Power Z4 Models)

Enhanced High-Power Capacity

With 185kW output (15kW higher than the Z4-250-12), this DC current motor handles heavier loads-ideal for large conveyors, heavy mining machinery, and high-torque processing equipment that require consistent, high-power delivery.

Wider Speed Range for Versatile Heavy Workflows

Its 1500/2200 rpm dual-speed design (200 rpm higher max speed) adapts to both steady low-speed heavy-load tasks and high-speed efficient operations, eliminating the need for separate motors for mixed-duty processes.

Stable 15V Excitation for High-Power Reliability

The optimized 15V excitation system maintains consistent magnetic field performance even under peak 185kW loads, reducing speed deviation and energy waste-critical for uninterrupted heavy-industry production.

Reinforced Build for Extreme-Duty Environments

Tailored for high-intensity workflows, its robust construction (aligned with industrial durability standards) withstands prolonged vibration and harsh on-site conditions, making it a long-lasting replacement for underpowered motors in heavy applications.

Brand-Backed Heavy-Industry Compatibility

As a Xi'an AIMIN flagship high-power model, it offers standardized mounting for easy retrofitting into existing large-scale systems, plus the brand's dedicated technical support for heavy-equipment integration.

For operations needing boosted power beyond standard Z4 DC current motor, the Z4-250-21 delivers the torque, speed flexibility, and durability to drive heavy industrial productivity.
