- Functional add-ons (e.g., brakes, oil seals).
Stepper motor Brushed motor Brushless motorRotating method Throughdriving circuitthe armature winding phases (two-phase, three-phase, five-phase) are excited in the order decided. By the sliding contact type of rectifying mechanism through the brush and commutator, switch the armaturecurrent. by using magnetic pole positionsensorsandsemiconductorswitches instead of brushes and commutators to achieve brushless.Driving circuit Need Not needed NeedTorque The torque is relatively large. (Especially the torque at low speeds) Large starting torque, torque is proportional to armature current. (The torque is relatively large at medium to high speeds)Rotating speed Proportional to the frequency of the input pulse. There are slip zones in the low-speed range. Proportional to the voltage applied to the armature. The speed decreases as the load torque increases.High-speed rotation High-speed rotation is difficult (need to slow down). limited by the commutator and brush rectifying mechanism, it can reach several thousand rpm High speeds of thousands to tens of thousands of rpm possibleRotating life Determined by bearing life. Thousands of hours Limited by the wear of the commutator and brushes. Hundreds to thousands of hours. Determined by bearing life. Thousands to hundreds of thousands of hours.Forward and reverse method The order of the excitation phase of the drive circuit needs to be changed Reversing the polarity of the input voltage to the pin The order of the excitation phase of the drive circuit needs to be changedControl; The rotation speed and position (rotation amount) can be controlled by command pulses in open loop (but there is a problem of loss of steps). Constant-speed rotation requires speed control (feedback control using a speed sensor). Since torque is proportional to current, torque control is straightforward.Difficulty of obtaining Easy: There are many varieties. Easy: Many manufacturers and varieties, many options. Difficulties: mainly dedicated motors for specific applicationsPrice The price is more expensive if the drive circuit is included. Cheaper than brushless motors. Relatively cheap, brushless motors are a bit more expensive because of the upgrade of the magnets. If the drive circuit is included, the price is more expensive
