• Light weight 107 grams with a diameter of 46.5 mm.
• Torque 0.14 Nm per ampere current.

How does a low speed brushless motor work?

The three phases of the windings create a rotating magnetic field. A rotor with 28 magnets follows the field. Low KV means low rpm with high torque. The hollow shaft allows wiring to pass inside. The motor rotates the robot's gimbal or wheel. The absence of brushes makes it very reliable.

Technical characteristics and functionality

The CubeMars GL40 model has a KV of 70 revolutions per volt. Motor size Ø46.5×21.5 mm. Configuration 24N28P (24 stator poles, 28 rotor magnets). The diameter of the hollow shaft is 8 mm. Motor weight 107 grams. Rated voltage 16 volts. No-load current 5 amperes. Phase-to-phase resistance 3.6 Ohm. Phase-phase inductance 1.8 mH. Torque per amp (Kt) is 0.14 Nm/A.

Imported 6700ZZ bearings are used. Protection degree IP45. Motor type – brushless (BLDC). Areas of application: robotics, gimbal systems (suspensions) and drives. Features: light weight, low magnetic resistance (cogging), low power consumption.

The engine is ideal for camera gimbals. Used in robot joints and manipulators. The hollow shaft is convenient for routing control wires. Low KV gives high torque at low rpm. Compact size fits into tight spaces.
