A stepper motor and gearbox in one, choose these motors when you want high torque but don’t have space for a large motor. Their planetary gearbox efficiently transmits power to increase torque while reducing speed. These motors are great for motion similar to a 3D printer head, using precise, repetitive movements. Like the hands of a clock, their shaft turns in small, equal increments. When the shaft stops, it holds its position, even if there’s a counteracting force on the load. You can control the position of the load without configuring encoders or sensors. All are bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors.

Holding torque is the force needed to move the shaft out of position when it’s stationary. When the shaft is in motion, torque generally decreases as speed increases. Use a torque-speed curve to confirm which motor will work for your application. Click on a part number and select “Product Detail” to view the curve for a motor.

Full step increment is the rotation of the shaft from one position to the next. The smaller the increment, the smoother and more precise the motion.

All motors require a controller and driver (not included).

Reduce the size and complexity of your stepper motor setup—these motors have a driver built in, so you don’t need to run cable to a standalone driver. The driver delivers power to the motor based on signals from a PLC, pulse generator, or other controller. These motors are good for precise, repetitive movements, such as those made by the head of a 3D printer. Similar to the hands of a clock, their shaft turns in small, equal increments for smooth motion. When the shaft stops, it holds its position even when a counteracting force is applied to the load. You can control the position of the load without having to configure encoders or sensors. All are bipolar hybrid stepper motors, so the current can flow in both directions. This helps them deliver higher torque, precision, and efficiency than unipolar stepper motors.

Holding torque is the force needed to move the shaft out of position when it’s stationary. When the shaft is in motion, torque generally decreases as speed increases. Use a torque-speed curve to confirm which motor will work for your application. Click on a part number and select “Product Detail” to view the curve for a motor.

Full step increment is the rotation of the shaft from one position to the next. A smaller full step increment means the rotor has more teeth, producing smoother and more precise motion. 1.8° is considered standard.

Reduce the step resolution to break a full step into smaller steps for smoother motion. For example, setting a 1/256 step resolution on your driver divides one full step into 256 smaller steps.

Often used for small automation applications, such as pick-and-place machines, these servomotors deliver lots of power in a small package. With accurate positioning and fine motor control, they create rotary motion based on signals from a drive (sold separately). The commands for speed and positioning are the same as those used for stepper motors, so you can upgrade your system without the hassle of reprogramming it. As these servomotors move, their encoder relays the shaft’s distance, direction, and speed back to the drive. The drive increases your system’s efficiency by taking the electrical signal from the encoder and dynamically adapting the motor’s movements, also accounting for inconsistent loads and unexpected forces.

Drives have several control modes that power the motor—step and direction, position, speed, or torque. Use a computer to set motion parameters and calibrate the servomotor to your system. After initial setup, you can use a separate controller, such as a programmable logic controller (PLC), microcontroller, or indexer. A brake resistor protects the drive from regenerated electricity as the motor slows or stops.

A built-in drive simplifies your servomotor setup, removing the need for cable between the motor and drive. DC servomotors are often used for small automation applications, such as pick-and-place machines, because they deliver lots of power in a small package. This system includes a motor, encoder, and drive for accurate positioning and fine control over speed and position.

These servomotors use the same step and direction commands as a stepper motor, so you can upgrade your current stepper motor system with this system. Use a computer to set up and calibrate the motor to your system. After initial setup, use a separate controller, such as a programmable logic controller (PLC), microcontroller, or indexer. The encoder relays distance, direction, and speed back to the servomotor. Based on this feedback, the servomotor dynamically adapts its movements to increase system efficiency.

Power supplies are designed to power servomotors, so they have tightly controlled voltage and high peak current output to support high performance motor control. They are capable of handling or dissipating regenerated energy as the motor slows or stops.
