What a hybrid stepper motor is
A hybrid stepper motor moves in fixed angular steps, typically 1.8° or 200 full steps per revolution, as a drive switches current through its windings in sequence. It combines a permanent-magnet rotor with toothed iron stator and rotor sections, giving high holding torque and fine resolution. With a microstepping drive, each full step is split into smaller steps for smoother motion. Steppers usually run open loop, so position is known by counting steps rather than measured.
When engineers choose a hybrid stepper motor
Choose a hybrid stepper for low-cost, simple positioning at low to moderate speed, such as indexing, dosing, small axes and instruments. It holds position strongly at standstill and needs no tuning. The trade-offs are falling torque at speed, resonance and possible lost steps if overloaded. Where speed is high, loads vary or a missed position would cause a fault, a closed-loop stepper or servo is safer.
How to specify the Leadshine 5-phase Stepper Motors (285CM / DM5 motors)
Send these with your enquiry and an engineer can confirm the right Leadshine 5-phase Stepper Motors (285CM / DM5 motors) variant:
- Holding torque (Nm)
- Torque needed at operating speed (Nm at rpm)
- Frame size (NEMA or mm)
- Step angle (°)
- Phase current and inductance (A, mH)
- Drive voltage (V)
- Shaft, encoder and IP options
Common mistakes to avoid
- Sizing on holding torque instead of the pull-out curve
- Driving with too low a supply voltage, losing high-speed torque
- Leaving out torque margin, typically 30% to 50%
- Ignoring resonance in the mid-speed range

What is the step angle of the Leadshine 5-phase Stepper Motors (285CM / DM5 motors)?
The published series maximum step angle is 0.72 °. Individual models and sizes in the Leadshine 5-phase Stepper Motors (285CM / DM5 motors) range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Why do stepper motors lose torque at high speed?
Winding inductance limits how fast current can rise each step. As speed increases there is less time per step, so current and torque fall. A higher drive voltage raises current faster and extends the torque curve. Always size from the pull-out torque curve at your drive voltage.
Does microstepping increase accuracy?
Microstepping makes motion smoother and gives finer resolution, but accuracy is not improved in proportion. Each microstep produces only a small torque increment, so load torque can shift the actual position. Accuracy is mostly set by the motor's step accuracy and the load.
