Mclennan introduce fully integrated motor with drive and control.

• Integrated microstepping motor and drive includes choice of on-board motion controller.
  
  
• Choice of simple or advanced controls increases application flexibility.

Ash Vale, Surrey, UK - December 2008 :
Mclennan Servo Supplies has launched a new range of NEMA 23 stepper motors with integrally mounted microstepping drives and a choice of on-board controls. The STM series from USA motion control specialist Applied Motion Products Inc is available in two lengths with stall torque ratings of 88 Ncm and 148 Ncm from a 12 to 70 VDC supply. The neat drive and control housing is rear mounted and includes all interfacing power and signal connections; making installation straightforward and reducing wiring time and cost over separate stepper motor + drive + control solutions.

The STM shares a common configuration and programming capability (and may be may be freely mixed) with all Applied Motion Products ST series standalone intelligent stepper drives which are available for torques up to 13 Nm and bus voltages to 320 VDC. The STM shares a common configuration and programming capability (and may be may be freely mixed) with all Applied Motion Products ST series standalone intelligent stepper drives which are available for torques up to 13 Nm and bus voltages to 320 VDC.

As with all ST series drives the STM power stage is fully protected and features selectable microstepping resolutions up to 51200 steps/rev, with advanced 20 kHz PWM current control, automatic anti-resonance waveform damping and torque ripple smoothing. The ST is available with two levels of control which both offer 3 digital inputs, 1 digital output and 1 analogue input. The STM-S version handles step and direction, CW/CCW pulse, A/B Quadrature encoder following and a basic level of host control using Applied Motion Products' SCL programming language. All configuration data is held in FLASH memory.

The advanced STM-Q controller version uses Motion Control Products' high-level Q programming language to write sequences of complex multi-tasked motion and machine control with full electronic gearbox, maths and registration functions. Q programmer software is also supplied free to create and edit stand alone programs. When fitted with the rear mounted encoder option, the STM may be programmed through the Q version to provide basic stall detection or a more advanced stall prevention measure that monitors motor command position to encoder lag and will finish its move under stall conditions. Configuration and program data is saved in FLASH and EEPROM memory Both S and Q control options include self test and auto setup routines to ensure optimal performance and fault-free operation. Configuration and program upload/download is made easy with Applied Motion Products' ST Configurator software.

Intelligent drive options for both stepper and servo technologies from Applied Motion Products may be combined to provide cost effective open and closed loop motion control systems. The range of control options includes open loop step and direction input, +/- 10V servo control, encoder following, graphical point and click programming for simple machine control and motion sequencing, and high level ASCII host control for complex multi-axis motion and machine control.

Mclennan introduce new microstepping drives.

• Higher bus voltage helps deliver more dynamic performance for microstepping drive.
• Choice of three intelligent drive types increases application flexibility.

Ash Vale, Surrey, UK - October 2008 :
A new range of high power/high speed microstepping drives, delivering up to 13 Nm of holding torque from a 320 VDC bus is now available from Mclennan Servo Supplies. The increased bus voltage on the STAC6, from USA based Applied Motion Products, effectively extends the power range of stepper drive technology and includes additional features that together derive improved performance from today's stepper motors.

The packaged drives are aimed at applications where the simplicity and comparatively lower cost of stepper motor control can replace servomotor positioning. Available in choice of S, Si and Q control versions covering simple step and direction, GUI based programming and host control with optional encoder following for multi-axis motion, the fully protected STAC6 series drive stage features advanced 20 KHz PWM current control with anti-resonance, torque ripple smoothing and waveform damping control algorithms - with programmable microstepping emulation to 50800 steps/rev for smooth dynamic performance.

Each control option offers a self test and auto setup for straightforward installation and the range is available with a choice of direct-on-line single-phase power ratings for 94-135 VAC delivering a 165 VDC bus, and 94-265 VAC input voltage for a 320 VDC bus. For such a high bus voltage, correct motor selection is imperative and the STAC6 series is available with laboratory tested and matched NEMA 23 and 34 frame stepper motors with best performance speed/torque information and selection advice available from Mclennan. Depending upon the motor characteristics, the drives may also be used to boost the performance of other manufacturers' motors and to improve existing performance limited applications without replacing the motor.

The Applied Motion Products range also covers intelligent servo and medium power stepper drives that utilise the S, Q and Si control options. Each control option includes a selection of I/O and a feature capability that ranges from basic pulse and direction control to multi-tasking software with conditional programming and maths functions. All drive technologies may be mixed and matched together with respective controls to suit the application and this flexibility can be extended further for multi-axis host control or standalone control with the SiNET Hub which allows up to four or eight S, Q, or Si drives to be configured, programmed and then networked with a PC, PLC or HMI in host or standalone modes.

Brushless DC motor with integral speed control electronics.

Ash Vale, Surrey, UK - September 2008 :
Mclennan Servo Supplies has released a new miniature brushless DC motor with integral drive electronics for precision speed control from Netherlands motor manufacturer Allied Motion/Premotec. This compact, high performance brushless motor with integrated speed control is ideal for small precision pumps, scanning heads, fans and medical devices.

Measuring just 32 mm diameter with a nominal length of 42 mm, the compact BL30 EB delivers an output torque of 30 mNm at 3500 rpm with an 11 W power output rating. The motor's outer rotor design ensures minimal cogging and a high-load bearing system and IP54 protection sealing makes it an ideal choice for small pumps, laser scanning heads, fans, medical devices and other applications where compact design, long life and high performance is essential.

The BL30 EB includes an integrated speed control loop with a speed-set input to adjust the motor speed from 200 to 5000 rpm. Available in CW and CCW variants with 12 VDC or 24 VDC supply, a two-wire version operates from a simple DC voltage and the four-wire alternative includes an 18 pulse per rev tachometer output for speed monitoring. The motor fully complies with EN 55014 for EMC and protection is included for reverse supply voltage and thermal overload with automatic recovery.

The BL30 EB is supplied with a 4 mm diameter x 12.5 mm long output shaft as standard with front- face spigot mounting with M3 fixing holes. Customised versions are available with special shaft modifications, alternate flange mounting, custom leads and connector configurations, as well as rear mounted encoders and gearbox options.

As with all motion control components and equipment supplied by Mclennan, the BL30 EB is available for evaluation from stock to ensure a fast delivery turnaround. The leading mechatronic specialist is also able to offer customised rotary and linear positioning assemblies based around the new motor using its own design, manufacturing and distribution capability.
