Nanotec has introduced a new series of high-torque compact stepper motors featuring optimized magnetics which it says contribute to achieving 15-30% more torque than in comparable motors.
Thanks to an improved stator geometry and optimized magnetic materials, the rotor inertia is no higher than that of the predecessor model. “The permanent magnet installed in the rotor is made of especially strong rare earth metals,” according to Alexander Naubert, project manager. “In combination with the soft-metal rotor plates, it forms a magnetic unit and, simultaneously, the magnetic antipole to the electromagnet in the stator.”
With a 56 mm flange and rated as NEMA 23, the SCA5618 series is available in three lengths and with two different windings. Depending on length, the holding torque ranges from 0.6 to 2.3 Ncm. It has a resolution of 1.8° but for a higher resolution, the motor can be combined with an optical or magnetic encoder.
As is characteristic with Nanotec products, it can be configured to suit a variety of applications and specifications. For example, it can be ordered with an 8 mm D shaft or with a round 6.35 mm shaft and, if more torque is required, it can be matched with the company’s newly developed GP56 high-torque planetary gearboxes.
Based in Feldkirchen, Germany near Munich, Nanotec was founded in 1991 and has grown to be a leading manufacturer of motors and controllers for industrial automation and medical engineering applications. The company has about 200 employees in Germany, Bulgaria, the USA and China and serves customers around the world.
Specializing in precise, high-performance drive solutions, Nanotec offers a broad range of integrated motors, brushless DC motors and stepper motors, as well as motor controllers and linear actuators that are primarily used in automation systems, automatic laboratory equipment and medical devices. It manufactures standard products as well as customer-specific designs.
Its stepper and BLDC motors, linear actuators and linear positioning drives, in sizes beginning at 10 mm, together with a variety of gearboxes and encoders, combine into a modular system with over 4,000 possible combinations. Additionally, customers can choose from a range of shaft, flange and connector types for linking to their existing device architecture.
