What are the features of a stepper motor?
Support » FAQ » Stepper motors
Stepper motors offer the following advantages:
- Step-accurate positioning without external linear encoder (open loop)
- Digital control pulses for speed and position
- The speed is proportional to the input frequency
- Step error (<5%) is not commutative (referred accordingly to 1.8 or 0.9 = +/- 0.09 or 0.045 )
- High torque even at lower speeds (compared to BLDC motors, gears can be frequently omitted)
- Simple and low-priced control electronics
- The high stiffness enables the rotor to remain in its holding position without requiring a brake. In addition, in stepper motors there is no hunting around the motor axis while the motor remains in its zero position which often leads to problems in servomotors.
- Excellent acceleration
- Maximum power density at low to medium speeds
- Can block without the windings being damaged
- High expected service life (brushless, therefore service life depends only on the bearings)
