Important notice - We will be performing system maintenance from 4pm Friday 19th April. Whilst we are performing this maintenance there will be no pricing available or ability to place orders. This will last for 2-3 days. Please contact customer support for any enquiries 0116 284 9900. We apologise for any inconvenience caused.
ELECTROMEN
EM-239 is designed for driving two actuators in parallel. The drive is done as synchronized according actuators pulse feedback signal. The synchronization is achieved by adjusting actuator speed during drive. If the adjustment cannot compensate the unbalance between actuators, the motors will be stopped. This way the mechanical stress and breakage can be avoided. Additively the driver includes current limit and power stage temperature limit. Driver works with actuators that can offer pulse feedback signal. Pulses can be derived from Hall-sensors, reed or other kind of switches. Driver can be set to read negative or positive pulses and also there can be selected two or one pulse line/motor mode. Driver power stage operates with PWM (pulse width modulation), that enables the high efficiency and low losses
of power stage. The basic control is done with FORWARD-, BACKWARD- and STOP-commands. FORWARD and BACKWARD can be done in continuous or in impulse control mode. In continuous mode the drive is done as long the command is on. In impulse mode the command impulses start and stop the driving. For help in assembly and in other special situations, driver has TRIM-inputs for controlling both actuators individually. With these control inputs the user can override most of the limits of normal use and balance the actuators or restore the normal driving position after some unexpected occurrences like
equipment failure or user in danger situation. HOME-command input is for driving the system in to its initial position. This driving is done with low speed and in to the end (in to the initial position). The counters are reset to zero. Wide range of parameters can be set to suit to different demands and different applications. In most cases the driver is ready to work with default parameters but some special features and behaviour can be accomplished with further parameter setting. One new feature is SAFETY REVERSE function, which automatically reversing when motors meet obstacle and will be overloaded
The parameters are set with a handy interface unit EM-236. There is also possibility to use EmenTool Lite PC-software with EM-268 and EmenTool App with smartphones for parameter setting.

At OEM Automatic, we can supply a series of components for your one project. All under one roof. This case study discusses how we supplied several components for our customer's new electro-pneumatic control box.
Technosoft specialise in developing intelligent drives and certainly live up to the term 'intelligent’, by combining a powerful motor and motion controller to implement complex movements.
One of the leading names in motors and drives, Oriental Motor, has signed a distribution deal with OEM Automatic. OEM Automatic can support customers, especially where an AC or Brushless DC (BLDC) motor has been discontinued or proving hard to source.
The Simplex Motion integrated servomotor is a brushless DC motor with integrated electronics and outrunner rotor. You can now browse Simplex Motion servomotors on our website.
OEM Automatic currently offers PMW’s range of standard pancake motors, as well as its bespoke design service. PMW’s motor portfolio caters for customers requiring both brushed and brushless configurations, supplied as housed or frameless, for both geared and direct drive applications.
DOGA’s new 311 and 311E is a right angle geared motor range, available with or without an integrated drive offering CANopen compatibility,
