Jershtech DC Motors
Precision brushless and specialty geared core components optimized for Portuguese smart appliances, medical automation, and energy-management infrastructure.
The Lisbon metropolitan region, encompassing major technology hubs from Oeiras to the Parque das Nações, has evolved into a center for technological innovation and industrial decarbonization in Southern Europe. Historically dependent on traditional assembly, Portuguese manufacturing is moving toward automated high-value engineering, specialized medical device design, and green energy technology. This shift has created a local demand for precision micro-motion control systems that meet European Union environmental and efficiency standards.
For Lisbon-based OEMs, product designers, and procurement managers, integrating small, high-density motors is no longer just about cost control. It is about aligning with the EU Ecodesign directives, reducing operational noise, and ensuring long-term product reliability. The 24mm Brushless DC (BLDC) motor has become a standard choice for these engineering layouts because it offers high power output in a compact size.
Modern B2B purchasing decisions require complete transparency regarding technical limits, winding specifications, and mechanical characteristics. The table below highlights the comparative metrics of the BL2418 and BL2430 micro series, which are commonly sourced for Lisbon's medical and smart-home engineering projects.
| Electrical Parameter | BL2418-S1 (Standard) | BL2430-H2 (High-Torque) | Testing Conditions & Standard |
|---|---|---|---|
| Nominal Input Voltage | 12 VDC (Range: 3.7V - 24V) | 24 VDC (Range: 12V - 24V) | ± 10% Constant Input |
| No-Load Current (Max) | 0.08 A | 0.15 A | No axial load applied |
| Rated Rotation Speed | 4,500 RPM | 7,200 RPM | At nominal torque output |
| Continuous Output Torque | 18 g.cm (1.76 mN.m) | 42 g.cm (4.12 mN.m) | T-N curve dynamic limit |
| Sensor Feedback Options | Hall Sensors (120° electrical phase) | Hall / Encoder / Sensorless (Custom) | Digital dynamic tracking |
| Insulation Safety Class | Class B (Up to 130°C) | Class F (Up to 155°C) | Under IEC 60034-1 testing |
Compared to brushed options, 24mm brushless motors utilize electronic commutation. By replacing physical carbon brushes with silicon drivers and neodymium permanent magnet rotors, these micro-motors solve two primary problems: electromagnetic interference (EMI) and friction wear. This results in cleaner electrical signals and a longer operational lifespan, which are essential for medical devices and telecommunication equipment in EU markets.
How our engineering services solve localized challenges in integration, compliance, and custom specifications.
We configure motor shaft flats, gear profiles, and custom mounting flanges (D-cut, cross-hole, threaded shafts) to integrate directly into existing Portuguese automation assemblies without requiring design modifications.
Integrated PCB filters and transient voltage suppressors ensure compliance with EU directives for residential and laboratory environments, reducing electrical noise issues.
Drivers featuring built-in PWM speed control, direction switching, and FG frequency generator outputs allow direct interface with low-cost microcontrollers, saving space on external driver boards.
The Direct Source for Precision Motion Control: Shenzhen Jershtech Technology Co., Ltd. is a China-based DC motor factory that designs and builds high-efficiency DC and BLDC motors to power robotics, automotive systems, medical devices, and smart automation globally. By integrating advanced manufacturing technology with rigorous testing, we provide global B2B clients with the quality verification of a local partner and the cost advantages of a direct manufacturer.

Importing precision drive systems into Portugal requires compliance with European safety and environmental standards. Shenzhen Jershtech ensures all motors shipped to Portuguese ports (including Lisbon and Sines) meet current regulatory requirements.
Each shipment of 24mm BLDC motors is accompanied by declaration certificates to streamline European customs clearance processes:
We work with established B2B freight forwarders to provide multiple delivery options to Lisbon-based production facilities:
As micro-automation requirements change, Jershtech continues to update its design and manufacturing technologies. Our current development focuses on integrating modern control and motor components:
Integrating compact magnetic encoders onto the motor's rear shaft allows for sub-degree positioning precision, suitable for robotic joints and medical dose controllers.
Using high-grade N52 Neodymium Iron Boron magnets increases overall output torque without expanding the physical size of the motor shell.
Using heat-conductive epoxy resins within the stator windings improves thermal dissipation, allowing for higher temporary peak current limits.
Detailed answers to technical questions commonly asked by micro-motion procurement specialists and engineers.
Our standard BL2430 brushless DC motor offers a design lifecycle of 20,000+ hours under continuous rated conditions. This is primarily limited by the ball bearings rather than brush wear. Brushed DC motors typically range between 1,500 and 3,000 hours of operation due to brush and commutator degradation, which also creates carbon dust contamination.
Yes. Shaft geometry customization is standard for our B2B clients. We provide custom shaft dimensions (e.g., standard round, D-cut flat, cross-drilled holes, or integrated helical gears) and can supply custom mounting configurations matching older European standards.
Our 24mm BLDC motors can be ordered with integrated drivers (providing a simple 5-wire interface: Power, Ground, PWM Speed Input, Direction Control, and FG Speed Feedback) or as a basic 3-phase stator configuration for use with external motor controllers, such as field-oriented control (FOC) systems.
At Jershtech, we use automated winding and balancing machinery to reduce variation in batch production. Additionally, we run coordinate measuring tests, salt spray evaluations, and full dynamic testing protocols on every production batch to verify performance parameters before export packing.
