Ever Motion Solutions Debuts UL-Listed MT Series Stepper Motors

Ever Motion Solutions has expanded its motion portfolio with the UL-listed MT series stepper motors, featuring a 2-phase hybrid design for high holding torque and precise positioning. Available in MT24 and MT34 frame sizes, the motors support currents up to 1000 A/ph and include optional integrated encoder feedback. Designed for global deployment, the MT series targets applications such as 3D printing, CNC equipment, and other motion systems where accuracy, torque, and cost efficiency are critical.

Stepping Into Motion

A stepper motor is a different kind of motor. A typical motor uses a single electrical power source and converts it to rotary motion using rotating magnetic poles. A stepper motor has each pole wired separately. This gives the motor the ability to rotate to a specific angle precisely and hold that position with high holding torque. Ever Motion Solutions is a supplier of all things motion-related, including brushless AC motors, drives, brushed DC motors, and integrated motors. The latest addition to the family of stepper motors is four new UL-listed hybrid dual-phase motors, featuring dual shafts, up to 1000 A/ph, and an integrated encoder.

The MT34 and MT24 Hybrid 2 Phase Stepper Motors

The new MT series motors from Ever Motion Solutions are equipped with a 1.8° per step and a maximum current range from 300 A/ph for the MT24 to 1000 A/ph for the MT34. The higher A/ph models are capable of higher steady-state holding torque. The rated voltage for all four models is around 3 VDC. This lower voltage is indicative of stepper motors, which reduce heat production at high current. One of the MT34 models is equipped with an integrated 1000 ppr incremental encoder with a 5VDC supply voltage. All four models are UL-listed, making them usable worldwide, and they all feature 2-phase hybrid technology.

2-Phase Hybrid Configuration

The MT stepper motor models are built using two motor technologies, an axially magnetized rotor and an electronically controlled stator. Internal reluctance sensors can measure the rotor speed and position via the stator. These technologies provide a stepper motor with greater accuracy, holding torque, and a smaller step angle. Stepper motors are commonly used in applications that require high accuracy and torque but are on a budget.

Desktop 3D Printing

Stepper motors are a lot like servo motors; you can command them to a specific position through the use of a motor drive, and they can output large amounts of torque. In a 3D printing application, each axis requires a motor capable of high accuracy and torque to move the print head through the workspace. While a 3D printer with servo motors would be very accurate, it would be very expensive. To keep costs down, manufacturers use stepper motors, and as the stepper motor industry advances, home desktop printers are becoming more affordable. Thanks to stepper motors like the MT series offered by Ever Motion Solutions, with their 2-phase hybrid technology, 3D printer or CNC manufacturers can provide their customers with more accurate machines capable of moving heavy loads.
