AC Drives

AC Drives convert fixed voltage and frequency into variable voltage and frequency to run AC motors.

Inverter (Open Loop)
Minarik Open Loop Inverter drives offer high starting torque, excellent shock load response, full torque to zero speed, and a wide range of control.  These characteristics make Minarik inverters ideal for continuous speed applications.

Open Loop Vector
Minarik Open Loop Vector drives, require no motor feedback and can be used to control speed or torque.  These drives provide high starting torque and excellent shock load response.

Vector (Closed Loop)
Minarik Closed Loop Vector drives require motor feedback and can be used to control speed and torque.  These drive provide high starting torque, excellent shock load response, full torque to zero speed, and a wide range of control.


DC Drives

DC drives convert an AC or DC power supply into a variable DC voltage to run DC electric motors. DC drives provide speed and/or torque control, controlled acceleration/deceleration, protect the motor from excess current

SCR
Silicon-controlled rectifiers (SCRs) are power devices used in DC drives to rectify AC voltage into DC voltage. SCRs are a diode with a gate (switch). When the gate is pulsed, the SCR turns on and allows current to flow through it uni-directionally.

PWM with IGBTs or MOSFETs
Insulated Gate Bipolar Transistors and Metal Oxide Semi-conductor Field Effect Transistor are transistor power devices. The transistor conducts in one direction only and turns off when the pulse goes to zero. The PWM chip in DC drives can generate high frequency switching

1-Quadrant Control

Minarik Single-Quadrant drives have the ability to control speed and torque in only one direction.

2-Quadrant Control

Minarik Two-Quadrant drives are only available in PWM based drives, and have the ability to control speed and torque in both directions.

4-Quadrant Control

Minarik Four-Quadrant drives have the ability to control speed in one direction and torque in both directions simultaneously.


AC Gearmotors

Nearly all types of AC motors have versions that include gearing-which is a speed reducer and torque multiplier all in one. Gearing that is built into the motor removes the burden and cost of having to design in external reduction devices to achieve the desired speed or torque.

Parallel Shaft (or In-line) Gearmotors

Parallel shaft gearmotors have the gear shaft in parallel with the motor shaft. They can be arranged in-line end to end or offset from the motor shaft.  The offset version is more compact and common than the in-line and allows for mounting flexibility because the location of the motor shaft on the motor face does not have to be in the center.

Spur and helical gears are common in parallel shaft, small horsepower gearmotors.

Right Angle Gearmotors

Right angle gearmotors have the output shaft at 90º to the motor shaft. They are usually used in applications where space is limited and an in-line shaft gearmotor can't be mounted. They are also useful in installations that require a vertical output shaft which is not recommended for in-line gearmotors.

Parallel Shaft (or In-line) Gearmotors

Parallel shaft gearmotors have the gear shaft in parallel with the motor shaft. They can be arranged in-line end to end or offset from the motor shaft (while still parallel). The offset version is more compact and common than the in-line and allows for mounting flexibility because the location of the motor shaft on the motor face does not have to be in the center.

Spur and helical gears are common in parallel shaft, small horsepower gearmotors.
