CubeMars AK45-36 KV80 BLDC Robotic Actuator

CubeMars AK45-36 KV80 BLDC Robotic Actuator

CubeMars AK45-36 KV80 is a BLDC robotic actuator for compact robot joints and articulated research mechanisms. Its 36:1 planetary reduction provides 8Nm rated output torque and 24Nm peak output torque, with 24V as the published supply reference.

The driven actuator combines the motor, planetary gearbox and motor-control electronics. Match the installed board, winding and software generation before commissioning: a similar motor name or reduction ratio does not make driver boards, firmware and connection leads interchangeable. RUBIK LINK is a separate accessory.


CubeMars Motor Application Guide

CubeMars motors and actuators cover humanoid joints, quadruped platforms, exoskeletons, custom frameless drives, gimbals and underwater propulsion. Application categories identify starting points; final selection depends on the exact model, control configuration and load case.

Motor Type Actuator Model Technical Description
Shoulder Joint Motor AK60-39 V3.0 A starting point for humanoid shoulder mechanisms and multi-axis arm motion. Evaluate arm inertia, payload, moment arm, output-bearing loads and duty cycle for each axis; the application label is not a verified complete-arm load rating.
Elbow Joint Motor AK70-9 V3.0 A candidate for robotic elbow flexion and extension. Match the complete arm load cycle, required output speed, mechanical envelope and feedback configuration before integration.
Wrist Joint Motor AK45-10 An option for compact wrist mechanisms. Compare end-effector mass, cable routing, output-bearing loads and the exact driver and feedback configuration for the selected version.
Neck Joint Motor AK40-10 A candidate for robotic head positioning. Check head inertia, joint geometry, movement range and feedback requirements; validate the assembled mechanism rather than assuming a motor alone establishes positioning performance.
Hip Joint Motor AKH70-48 V1.0 A starting point for humanoid hip mechanisms. Evaluate body mass, gait-dependent torque and speed, transmission geometry, thermal duty cycle and mechanical margins for the complete leg.
Knee Joint Motor AK80-64 An option for knee flexion and extension mechanisms. Check the torque profile throughout the motion cycle, required speed, impact loading and thermal demand before selecting the joint assembly.
Ankle Joint Motor AKH70-16 V1.0 A candidate for robotic ankle mechanisms. Evaluate foot geometry, ground-contact loads, motion range and system-level balance-control requirements separately from the actuator specification.

Features

  • Model-specific output sizing - 8Nm rated output and 24Nm peak output distinguish normal design loading from short transient demand. Evaluate the real torque-speed cycle, cooling and driver limits.
  • Defined planetary reduction - 36:1 is the mechanical reduction ratio for AK45-36 KV80. Compare it with required joint speed and reflected load inertia rather than selecting by motor diameter alone.
  • Supply-dependent performance - 24V is the published supply reference. Size the complete power path for the actual supply and operating current.
  • Driven actuator configuration - The motor selection includes the integrated driver; the separately listed RUBIK LINK interface is used for setup and is not another motor.
  • Feedback matched to the hardware - Single magnetic encoder reference for the With Driver assembly; resolution is not axis accuracy; verify the firmware and feedback configuration before enabling motion.
  • Backdrive behavior - 0.8Nm is the listed resistance to externally driven rotation. It is not output torque, a brake holding rating or an automatic safety function.
  • Transmission clearance - 12 arcmin is the gearbox backlash reference. It is not complete-axis positioning accuracy and should be included in the mechanical error budget.
  • Board-specific commissioning - AK40-2410-1A-A1 is the manufacturer's driver reference for this model. Confirm the board label and matched instructions before wiring or changing firmware.
  • Thermal and duty-cycle planning - Rated and peak figures require an appropriate mounting and cooling arrangement. Continuous stall, impact loading and repeated acceleration should be verified with the actual mechanism.
  • Engineering resources by configuration - Matched drawings, available software and model-specific support files are grouped below. Use the exact winding, driver revision and firmware family; a newer-looking filename is not evidence of compatibility.

CubeMars AK Selection Guide

Integration Need Models to Compare Selection Checks
Compact24V joint AK40-10 / AK45-10 / AK45-36, keeping generations separate Compare output torque, rated speed, reduction ratio and actual driver generation. V3.0 and older models can differ in feedback and envelope even when nominal torque is similar.
Low-ratio dynamic axis 6:1 / 8:1 / 9:1 / 10:1 models Select the torque-speed operating point and reflected inertia before considering peak torque. Check the actual supplied driver and feedback configuration.
Higher-ratio geared output AK45-36 / AK60-39 / AK80-64 36:1 / 39:1 / 64:1 reduction changes output speed, backdrive behavior and the application error budget. Check torque, bearing loads and heat rejection together.

Application

Articulated robot joints

Size the complete joint against its torque-speed cycle, mechanism geometry and output-bearing loads.

Legged-robot research

Evaluate gait-dependent peak demand, impact loading, structural stiffness and installed thermal limits.

Exoskeleton prototypes

Develop powered joints with independent torque limiting, mechanical stops and application-specific human safety validation.

Assistive-mechanism development

Combine the actuator with the required sensing, guarding and controlled motion envelope; a motor is not a certified medical system.

Laboratory actuator test rigs

Measure current, temperature, backdrive behavior and response with the actual selected driver configuration.

Custom automation axes

Check the transmission, coupling, mounting and controller interfaces before integrating the complete rotary mechanism.

FAQ

What is the CubeMars AK45-36 KV80 used for?

AK45-36 KV80 is intended for compact robot joints and articulated research mechanisms. Final payload, accuracy and safety depend on the complete mechanical and control system.

Does the motor selection include a driver?

The driven motor selection includes the actuator driver. Motor (w/o Debug Board) means the external RUBIK LINK debug accessory is not bundled with the motor; it does not mean the actuator driver is absent.

Is RUBIK LINK a motor-and-debug-board bundle?

No. The RUBIK LINK option is a standalone commissioning interface. Select the actuator or the interface as separate items; a debug adapter is not a motor driver or another motor.

What are the torque, supply and reduction references?

24V, 36:1 reduction, 8Nm rated output and 24Nm peak output are the published model references. Peak torque is not a continuous-duty allowance.

Are older AK drivers and V3 drivers interchangeable?

No blanket interchangeability is specified. Check the board label, connectors, motor winding, feedback and software family before changing wiring or firmware. Keep older AK driver resources separate from V3 resources.

Does encoder resolution establish joint accuracy?

No. Encoder resolution, gearbox backlash and assembled-axis accuracy describe different things. Match the feedback hardware and assess the complete error budget rather than treating a bit count as a positioning guarantee.

How should I interpret the rated speed?

The rated output speed is 40rpm. Use the stated supply and load reference. No-load speed is a different operating condition.

Can I use the peak output continuously?

No. Validate motor temperature, heat removal, driver current limits and the actual operating cycle. Repeated acceleration, impact loads and continuous stall require separate system-level evaluation.

What does the packing list cover?

The motor section covers the selected actuator configuration and the verified connection items. The separate RUBIK LINK section is not an extra motor in the actuator kit.

Which engineering and software files should I use?

Use the matched mechanical drawings and the instructions for the actual installed board, winding and feedback hardware. Firmware, software and historical driver references are not interchangeable simply because they are downloadable from the same brand.
