Description
140-E Series BLDC Motor
The 140-E Series permanent-magnet brushless DC motor is engineered for construction machinery that needs compact low-voltage power, controlled acceleration and dependable daily operation. Its round cast-aluminum mounting flange, hollow spline output, ribbed housing and matched electronic control make it suitable for loaders, excavators and utility equipment.
Built for Construction Equipment
The 140-E motor integrates into compact loaders, excavators, utility vehicles and other electric construction platforms where installation space is limited and repeatable low-voltage drive performance is essential.
- Round cast-aluminum flange with multiple mounting points
- Hollow spline connection for compact transmission integration
- Gold ribbed aluminum housing for strength and heat dissipation
- Custom flange, cable and connector configuration available
Reliable in Tough Conditions
A robust aluminum body and brushless structure support daily operation in construction environments with dust, vibration and repeated start-stop cycles. The reference motor configuration can be specified to IP67, while final protection also depends on connectors, seals and installation quality.
Application details should be confirmed for ambient temperature, contamination exposure, shock loads, duty cycle and required enclosure protection.
Strong Torque for Demanding Tasks
Permanent-magnet BLDC technology combines smooth starting with responsive electronic control and stable output under changing loads. Correct controller matching helps the 140-E motor handle frequent acceleration, deceleration and repeated working cycles.
Supply voltage, operating current, peak torque demand and acceleration profile are matched to the machine before production.
Efficient Cooling Design
Longitudinal ribs increase the aluminum housing’s heat-dissipation area, while the ventilated blue rear cover supports airflow around the cooling section. This compact thermal design helps maintain stable operation when the motor is correctly installed within the machine.
- Ribbed aluminum housing for improved heat transfer
- Ventilated rear cover supports cooling airflow
- Compact cylindrical structure for limited installation spaces
- Accessible external layout for inspection and maintenance
Integrated BLDC Drive System
A complete solution can include the motor, matched controller and application-specific wiring harness. Coordinated electrical components simplify equipment integration and help ensure that voltage, current, connector and control requirements are aligned.
- APM350 Series controller reference configuration
- 48–72 V low-voltage electrical platform
- Power cables, signal wiring and connectors available
- Custom cable length and connector layout supported
Tested for Consistent Performance
Electrical inspection, load testing and a final condition check help verify the motor before shipment. Testing can be adapted to the confirmed voltage, controller, duty cycle and mechanical interface of the ordered construction-machinery configuration.
For OEM projects, provide the equipment type, supply voltage, target power, installation space, output interface, controller requirement and expected order quantity.
