Nanotec has introduced a driver for stepper and brush-less dc (BLDC) motors with sensor-less closed-loop and field-oriented control (FOC). Intended for steppers from NEMA 14 to NEMA 34 and BLDC motors up to NEMA 23 “its sensor-less closed-loop control provides precise management of torque and speed”, according to the company. A additional ‘safe torque off’ (STO) function is in the ...

No-volt release with few new holes?
Some sort of sane no-volt release and emergency stop needs to be applied to the cnc lathe project (when time allows….) And before that time is available, so thought has to go into what arrangement is acceptable. Find more cnc lathe project blogs here It seems a shame to cut too many more new holes in the front, and certainly ...
Click board includes 85V 10A stepper motor driver
Mikroe has added a smart 85V 10A stepper motor driver to its range of interchangeable ‘Click’ boards. Called Power Step 2 Click, the board “is based on the powerSTEP01, a 1/128 microstepping controller from STMicroelectronics that integrates eight n-channel mosfets with ultra-low Rds(on)”, according to Mikroe. “It features a 5MHz SPI interface, multiple safety protections, and additional control pins for ...
Stepper motors with large bore hollow shafts
Moon’s Industries has created a family of stepper motors with large-bore hollow shafts. There are five basic motors, ranging from 36 x 36mm (7 or 12mm bore) to 60 x 60mm (27mm bore): size (mm) 36×36 42×42 57×57 60×60 Shape round square square square square Bore (mm) 7 12 16 22 27 All of the motors measure 21mm from front ...
NEMA23 stepper motors with UL/CSA certification
Nanotec has introduced UL/CSA certified 56mm flange (NEMA23) stepper motors with integrated position encoders. There are four ASA5618 motors, giving options on 140 or 230Nm torgue (which corresponds to 88 or 109.5mm length) and either a incremental (4,096 CPR / 16,384 PPR) or multi-turn (16bit multi-turn, 17bit single-turn) encoder. Current per winding is 4.2A and ingress protection is to IP65. They are ...
Shhh… gearboxes are quiet for NEMA 17 motors
Nanotec has created low-noise planetary gearboxes for brushless DC and stepper motors with NEMA 17 flanges (42mm, 1.7in). “With the GP42-N series,” according to the company, “the helical toothing allows the teeth to mesh gradually, which results in a smoother transmission of forces so that vibrations and noise are reduced.” The use of plastic planetary and ring gears also contributes ...
NEMA 6 linear actuator is only 14mm across
Nanotec has introduced its first linear actuator with a NEMA 6 stepper motor – the flange is only 14mm across. “This compact unit is ideal for applications with space restrictions, such as medical or analytical instruments, or lab automation and optical applications,” according to the company. Called LSA14, there are two versions; Acme and trapezoidal (see table below), with the ...
1.2A stepper driver in 4x4mm package needs no external sense resistor
Toshiba has launched an 4 x 4mm QFN24 stepper motor driver that can run from 4.5 to 33V and deliver up to 1.2A. Typical on-resistance of the output block is 1.2Ω. “It is well suited for constant-current control stepper motor applications including those found in office automation, commercial and industrial equipment. It is also suited for surveillance cameras and projectors,” said ...
Motor controller programmes through Arduino IDE
ClearCore CLCR-4-13 is an industrial IO and motion controller that can be programmed using the Arduino IDE. It handles up to four axes of step-and-direction motion control (500kHz max step rate), and provides 13 software-configurable protected 24V-compatible I/Os. “You can download the optional ClearCore Arduino Wrapper Library. This allows you to write code within the easy-to-use Arduino IDE and using Arduino ...
Board turns a stepper into a servo
Trinamic Motion Control claims to be making the “smallest single-axis servo controller-driver module with integrated motion control”. TMCM-1321, as it is known, controls two-phase bipolar stepper motors and includes a magnetic encoder and digital inputs for an optical encoder. It is a 28 x 28mm module, although it needs more space than this because “it is recommended to connect an ...
