Description
SPA Android Technics has many years of experience in the production of electric motors. The company mass-produces high-torque synchronous brushless electric motors with permanent magnets of the AT Drive series in framed and unframed versions with power from 60 W to 10 kW.
The advantages of the design of electric motors include the possibility of their direct integration into products for various purposes, efficient heat dissipation and reduced complexity of drive manufacturing.
The technical characteristics of the electric motor make it possible in certain cases to design a gearless circuit, which multiplies the life cycle of the product in which the electric motor is installed. In addition, AT Drive series electric motors are highly energy efficient, which will reduce costs for the end user.
SPA Android Technics also develops analogues of imported electric motors as part of import substitution and creates new standard sizes according to customer needs.

Note:
Designation T – high-torque series
The length of electric motors with the designation T is indicated without Hall sensors
The inductance will be measured after fabrication
* Under development, specifications are planned
Application
Brushless electric motors can be used in devices such as:
- Small industrial robots and collaborative robots
- Pivoting devices
- Anthropomorphic and biomorphic robotic complexes
- Active exoskeletons
- Unmanned underwater vehicles
- Aviation
- CNC machines
Advantages
AT Drive series brushless synchronous DC motors have a number of advantages:
- The best-in-class indicator of specific torque (rated and peak)
- Indicators of specific power and efficiency of electric motors are at the level of the best world standards
- The ability to control the rotation speed in a wide range
- High positioning accuracy and no «bounce» when fixing the shaft positions
- The product is compact - wide possibilities for arrangement and design of robotic complexes
- It has successfully passed the test in space as part of the robotic complex «FEDOR» on the ISS
Особенности
Distinctive features of the AT Drive series of brushless electric motors:
- The stator winding compound is resistant to thermal shocks from -60°C to +170°C (on request, electric motors may be manufactured for another version)
- The design of the electric motor allows its installation in products for various purposes
- Operation both under normal conditions and in aggressive environments (water, oil, acids)
- Operation in radiation fields
- The possibility of changing the method of connecting the windings
- High peak torque rating
- Frameless design and hollow rotor
