CubeMars RI70 KV95

The stator edge has been specially designed with a 0.5 mm spacing, allowing for precise standard positioning and easy installation. Thanks to its high slot fill rate, the motor is ideal for applications requiring high torque density and significant power output. The motor's back electromotive force (EMF) has a sinusoidal shape – making it suitable for use in simple servo applications.

The overall rotor height has been increased by 2 mm to improve induction between the rotor and Hall sensor – especially in cases where the Hall sensor is installed by the customer. The motor offers precise control, enabling high resolution and accuracy – up to 0.01° – when used with high-precision encoders from manufacturers such as Renishaw, Sike, and others.
