Product description

The GL40II is a hollow-shaft gimbal motor with an integrated driver board. It is designed for applications that need smooth rotation at low speeds.

Key features

  • Cogging torque reduced by 30%. Less vibration at low speed and smoother rotation.
  • Optimized electromagnetic design. Raises efficiency and lowers power draw and noise.
  • Integrated driver board. Motor and driver come together as one system, with no separate board.
  • Hollow driver board. Supports CAN and PWM communication, and cables can pass through the center.
  • Three control modes. Works in MIT mode, position mode with speed, and speed-only mode.
  • Hollow shaft. Makes internal wiring easier and improves system integration.

Applications

Typical applications include gimbal systems, camera tripods, precision rotary axes and compact robot mechanisms with internal wiring.

Is it enough for your project?

The GL40II is a small gimbal motor with the driver built into its housing, delivering 0.25 Nm continuous and 0.68 Nm peak torque. In a well-balanced gimbal the motor does not carry the whole load, only the imbalance and the inertia during acceleration. For example, if a 300 g camera sits 5 cm off its center of gravity, it needs about 0.15 Nm of static torque (0.3 × 9.81 × 0.05). That stays within the motor's rated torque.

At 125 g and 46 mm in diameter it suits light cameras, small pan-tilt mechanisms and sensor and radar heads. The reduced cogging gives vibration-free footage in slow tracking moves.

How it compares to similar models

  • GL60II KV28. Designed for heavier loads with 0.6 Nm rated and 1 Nm peak torque, weighing 276 g.
  • RO60 Lite KV115. A frameless torque motor with 0.8 Nm rated torque. The driver and encoder are chosen separately.
  • AK40-10 KV170. A geared actuator with 1.3 Nm rated torque. It is designed more for small robot joints than for gimbals.

Frequently asked questions

Is the driver included?

Yes. The driver board is inside the motor and supports CAN and PWM communication.

Which control modes does it have?

It works in MIT mode, position mode with speed, and speed-only mode.

What voltage does it run on?

The rated operating voltage is 16 V. At that voltage its no-load speed is 1,388 rpm.

Where do the cables go?

The shaft and driver board are hollow, and cables can pass through the center of the motor.

Frequently asked questions

The most common questions about motor selection, delivery and technical support.

Is the product in stock and when is it dispatched?

Our products ship from our own warehouse in Turkey. Your order is dispatched within 3 business days. Current stock status is shown on this page.

Which motor fits my project? Can you help me choose?

Yes. Tell us the torque, speed and supply voltage you need, and we will find the right series together. You can also compare using the specifications table on this page and the filters on the category page.

  • For high torque at low speed, the AK, AKE and AKH series with gearbox
  • For direct drive and low inertia, the frameless RI and RO series
  • For cameras and stabilization systems, the GL series
Are the products genuine and under warranty?

Robotizma is an official CubeMars distributor. Every product we sell is genuine and covered by the manufacturer's warranty.

Where can I find the datasheet and mounting dimensions?

The Specifications section on this page lists rated torque, peak torque, KV, no-load speed, weight and outer dimensions. If you need the detailed datasheet, CAD file or driver documentation, ask our technical team.

Do you offer corporate sales, quotes and invoices?

We sell to universities, industry and R&D projects. For volume pricing and a formal quote, fill in the Request a quote form on this page and our team will reply with price and delivery details.

Which driver and communication can I use with the motor?

In the AK and AKH series actuators the driver board is built into the motor and communicates over CAN. The AKE series and the frameless RI and RO series motors need an external FOC driver. The R-Link and S-Link interfaces are for setup and debugging, and we can support you during installation.
