Why Engineers Search for an Integrated Joint Actuator Price List

When robotics engineers and procurement teams look for a price list for integrated robot joint actuators, they are usually solving a larger problem than unit cost. They need to know what sits inside the housing, how much torque the module delivers, how it communicates with the rest of the system, and whether it can be dropped into an existing platform without redesigning the wiring harness. VAXOR-MOTOR structures its commercial approach as product-based sales for standardized modules across the X16, X20, X25 and X30 series, and supports that offer with detailed technical specifications and test data for electric drive assemblies, covering performance parameters such as torque, speed and thermal data. A specification-first comparison therefore tells buyers more than a number on its own.

The Technology Platform Behind VAXOR-MOTOR Modules

VAXOR-MOTOR/VAXOR is positioned as a provider of integrated micro-actuation solutions, specializing in axial flux motors, cycloidal gear reducers, and non-contact encoder integration. The company addresses a well-known industry pain point: the demand for high torque density, precision and compact footprints in micro-manipulation and high-load robotic applications.

Technical Metrics That Drive Selection

The core differentiated advantage comes from combining axial flux motors with micro cycloidal reducers, which supports both torque density and rigidity. On the electromagnetic side, designs optimize phase imbalance to within 5%, which underpins yield and power density. Across the platform, key figures include:

• Actuator diameters ranging from Φ16mm to Φ30mm
• Phase imbalance controlled within 5% for ultra-micro motors
• Gear efficiency reaching up to 75% for specific modules
• Backlash as low as 15–20 Arcmin

These values are produced through a modular design architecture and optimized electromagnetic design for brushless and coreless systems.

Communication, Interfaces, and Bus Compatibility

Platform compatibility covers 12V, 24V and 48V DC bus systems. Communication options include SPI and CAN FD, and the standardized interface is an FPC 7PIN (0.5mm pitch) connector supporting VCC, GND, CS, SCK, MOSI, MISO and CAL (calibration).

Module-by-Module Review of the Joint Actuator Line

Φ16mm Micro Joint Module (X16S / X16L)

Positioned for precision micro-manipulation in highly integrated robotic systems, this unit is notable for compact weight — as light as 24.3g (S-version) or 26.1g (L-version). Torque performance reaches a continuous stalling torque >7.1 mNm and a stalling torque (max) >16.5 mNm. Integrated gear reduction is available in ratios of 30, 40 and 50, delivering high torque in a 16mm diameter footprint. An absolute magnetic encoder provides precise position feedback for high-precision motion control, while SPI communication supports low-latency control response. Thermal management is defined by chassis temperature limits of 80°C/115°C/145°C based on power loss. Delivery model: hardware module.

Φ20mm Micro Joint Module (X20S / X20L)

Aimed at medium-load precision actuation for bionic and automation applications, the X20 series delivers continuous stalling torque >17.2 mNm and stalling torque (max) >35.3 mNm. It supports 12V/24V/48V operation. The multi-ratio gearbox offers 15, 30 and 50 ratios, balancing speed against torque requirements, and the assembly reaches up to 450 mNm at ratio 50. The FPC 7PIN interface standardizes wiring for power and data, simplifying integration into robotic limbs.

Φ25mm Micro Joint Module (X25S-UZ / X25S-BZ)

Designed as a high-torque actuator for industrial and medical robotics, the X25 series uses the CAN FD protocol for robust industrial environments and reaches continuous stalling torque up to 1150 mNm (Ratio 50). Reduced backlash of 15 Arcmin supports motion accuracy, and torque capacity reaches 1800 mNm (initial torque, cold state) for peak load scenarios.

Φ30mm Micro Joint Module (X30S-UZ / X30S-BZ)

For heavy-duty micro-robotic applications, the X30 series reaches continuous stalling torque up to 1500 mNm (Ratio 50) and up to 75% gear efficiency at ratio 30. CAN FD integration supports complex network architectures for multi-joint robots, and a total inertia of 30.4 gcm² provides stability in high-load motion.

G04P, G05P and G06P Ultra-Micro Brushless and Coreless Motors

The ultra-micro motor line targets medical robots, drones and wearables. The G04P/G05P/G06P series addresses the high cost and low yield typical of sub-6mm motor production through ultra-lightweight construction (1.7g to 3.75g) with speeds up to 63,000 RPM. No-load speeds range from 55,000 to 63,000 RPM, suited to micro-pumps and drones. Chassis temperatures up to 145°C are supported, and terminal resistance as low as 1.6Ω improves electrical efficiency. Phase imbalance within 5% reduces costs and improves reliability. Industry adaptation spans medical micro-surgical robots, precision optical adjustments, and miniature haptics and pumps in consumer electronics.

Application Evidence Across Robotic and Industrial Systems

• Robotic dexterous hands: X16 and X20 modules were used to achieve high-integration mechanical motion control, enabling human-like finger dexterity.
• Industrial automation: Φ30mm modules integrated into precision transmission systems achieved gear efficiency of 75% and reduced mechanical backlash to 15 Arcmin.
• Micro pump systems: G05P ultra-micro motors at 55,000 RPM drove fluid transmission in medical and consumer applications with low cost and high power density.
• Photon optics: Ultra-micro brushless motors supported precision positioning in optical instruments, benefiting from <5% phase imbalance for stable performance.

Delivery Model, Documentation and Support

Deployment combines hardware integration with standardized FPC 7PIN interfaces or CAN FD/SPI communication protocols. Alongside the hardware comes technical integration support, including specifications and test data for electric drive assemblies, and after-sales engagement covering technical inquiries and discussions regarding product specifications and operational parameter ranges.

Matching the Right Module to the Load

For buyers comparing integrated robot joint actuators, the practical decision path is to start from the load and envelope: Φ16mm where weight and integration density dominate, Φ20mm for medium-load bionic joints, Φ25mm for high-torque industrial and medical axes, and Φ30mm where network complexity and inertia handling matter. Paired with the G04P/G05P/G06P ultra-micro motors for pump, photonics and haptic duties, the VAXOR-MOTOR matrix covers the actuation and medium transmission needs of sophisticated robotic and industrial systems.
