The CVK Series features one of the smallest, standard microstepping drivers combined with a 1.8° 2-phase bipolar high-torque stepper motor for the optimum motor performance. Since the driver size, installation and I/O connectors are the same, it is easy to evaluate the motor based on the application requirements. The 1.8° 2-phase CVK Series features the highest motor torque in the low speed range and with the fully digitally controlled microstepping driver, all CVK Series motors feature low vibration throughout the entire speed range.
The CVK Series is also available as a 0.36° or 0.72° 5-phase stepper motor package that features higher positional accuracy or higher torque at mid to high speed
Five frame sizes are available; 0.79 in. (20 mm), 1.10 in. (28 mm), 1.38 in. (35 mm), 1.65 in. (42 mm), and 2.22 in. (56.4 mm).
Revisions to the stepper motor winding design and a high-efficiency driver circuit design allow for significant torque increases in the low-speed range. In particular, torque in the 250 r/min range has been increased by 50% compared to conventional products allowing for quicker moves.
The maximum holding torque has increase with a bipolar winding.
Vibration and noise have been greatly reduced compared to conventional 1.8° stepper motor performance. The vibration characteristics have been significantly improved across all speed ranges with the fully digital-controlled microstep driver.
The new smooth drive control with higher current control increases the basic step angle to a maximum of 2048. As a result, a reduction in step vibration in the low speed range is achieved.
The maximum holding torque in the low-speed range is achieved with the 1.8° stepper motor and driver packages through the use of a high motor current design and specification. The speed range has increase considerably with the 0.36°/0.72° packages.
The size, installation and I/O connectors for the CVK Series 1.8° and 0.36°/0.72° stepper motor and driver packages are the same. Because of this, it is easy to evaluate and select the proper package for your specific application.
*The driver for a 1.8° stepper motor and the driver for a 0.36°/0.72° stepper motor are not interchangeable. Each motor type has a dedicated driver.
It is easy to try 0.72° or 0.36° motor and driver without any changes to your 1.8° pulse input as the driver has a step resolution switch to allow for setting of input to output resolution. Simply choose a 0.36° or 0.72° package (driver mounting is the same) and use the step angle setting switch to match the existing input pulses to the desired output speed and position. There is no software or control module required.
A high-torque stepper motor with 50% more torque at the low speed range than a 1.8° standard stepper motor.

Build a complete system online by selecting your base stepper motor and driver and adding all necessary accessories and/or controller.
This three-piece coupling adopts an aluminum alloy hub and a resin spider. The simple construction ensures that the high torque generated by a gear motor can be transmitted reliably. The proper elasticity of the spider suppresses motor vibration.
Mounting brackets are convenient for installation and securing a stepper motor or geared stepper motor.
