The available torque from a stepper motor falls off sharply as speed increases. The maximum torque is available when the motor is stationary. Using a higher motor power supply voltage will improve torque at higher speeds.
How do you increase torque?

What happens to speed when you increase torque?
If you increase the torque you increase the speed UNLESS you increase the load. The important thing to remember is that with electric motors there is a back-EMF (a motor is a generator too) which increases with speed and that limits the effective voltage and thereby the current and thereby the torque.
Does microstepping increase torque?
The lure of microstepping a stepper motor for precision must be tempered by torque considerations. The graph shows that at 16 microsteps/full step, the incremental torque for one microstep is less than 10% of the full-step holding torque. MicroMo Electronics Inc.
How strong is a NEMA 17 stepper motor?
This NEMA 17-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in).
Why do stepper motors have high torque at low speeds?
Providing higher voltage to the motor windings effectively pushes the torque-speed curve “out,” resulting in higher torque production at higher speeds.
Is higher torque holding better?
The amount of power the motor needs to produce to overcome the detent torque is proportional to the motor’s speed. So the faster the motor turns, the greater the effect detent torque will have on the motor’s actual torque output. … Therefore, a higher detent torque will help the motor stop more quickly.
Which torque is highest in stepper motor?
High Torque Stepper Motors from 0.01 to 50Nm. NEMA08,NEMA17,NEMA23,NEMA34,NEMA43,NEMA53. A series of step motors that have been designed by JVL for use with the entire range of JVL Step Motor Drivers and Controllers. They are high torque step motors especially made for mini- and microstep operation.
How long do stepper motors last?
The typical lifetime for a stepper motor is 10,000 operating hours. This approximates to 4.8 years; given the stepper motor operates one eight-hour shift per day. The lifetime of a stepper motor may vary in regards to user application and how rigorous the stepper motor is run.
Are stepper motors High Torque?
These stepper motors provide the highest torque in a wide range of frame sizes. For many applications, these motors offer a high-performance, cost-effective alternative to pneumatic, hydraulic and servo motor systems.
Do stepper motors have high torque?
Stepper motors remain popular for industrial motor applications because they are low-cost, rugged, simple, have high torque at startup and low speeds, require little maintenance, and they can operate in an open loop control system.
