Stepper motors

Stepper motors are often the designated solution for positioning applications. The angular warp is determined by the powered coil and the steering knows by counting where the motor is positioned. The frequency with which a subsequent coil is powered determines the speed. The electric current determines the power but does not influence the speed and position.

Stepper motors furthermore deliver very high quality coupling at low speeds. When correctly applied, they are the only motors where the speed can be adjusted from 0 rpm.

General specifications stepper motors

• coupling up to 12 Nm
• amplifiers for 24 - 160 V DC and 230 V AC
• micro stepping resolution to 125,000 steps per revolution
• options: gear boxes, encoder, controller
• standard products, quick supply

Rotero can assist with the following types of stepper motors:

• 2 phase: accurate, compact, favourably priced, long lifespan
• 5 phase: very accurate, less vibration
• closed loop: more reliable under variable loads
• with integrated controller: simple cabling and easy to use
• with spindle (linear stepper motor):creates a compact, strong and accurate linear actuator
