Abstract: A vehicle drive assembly includes an electric motor directly coupled to a rotatable member for driving a wheel, for example, without gear reduction assemblies between the motor output and the driven wheels. A multi-phase, high pulse current stepper motor is used as the motor in one example. A driven wheel is supported by a wheel mounting member in a conventional fashion. A rotatable member associated with the wheel mounting member is directly coupled to an output of the stepper motor. The stepper motor can selectively operate in several modes. A first mode provides driving torque to the vehicle wheels, a second mode provides a braking force and an optional third mode allows the stepper motor to serve as a parking brake.

Abstract: In this system, a controlled rectifier converter interconnects an alternating current voltage source with an AC induction motor. To effect voltage amplitude control, trigger signals are pulsed to the various controlled rectifiers of the converter during their respective 120* conductive intervals. The resultant duty cycle modulation affords control of the level of the voltage applied to the induction motor. At low frequencies, a plurality of power pulses are provided by the converter during each 60* of conduction, whereas at high frequencies, a single power pulse is supplied for each 60* of conduction. A smooth transition is provided between these two operating modes to ensure smooth, continuous motor control and operation throughout the operating range of the motor. This smooth transition is facilitated by synchronizing the power pulses in relation to the two 60* increments comprising the 120* conductive intervals for the respective controlled rectifiers.

Abstract: 1,136,253. Magnetic amplifiers. LANSING BAGNALL Ltd. 12 July, 1966 [14 July, 1965], No. 29898/65. Heading H3B, [Also in Divisions G3, H1 and H2] A transductor, for applying a variable proportion of the pulses from a multi-vibrator and shaping circuit to the firing circuit of a thyristor in circuit with an electric motor, comprises cores 12, 13 separated by air gaps 16, 17 wich a reactance winding 18 around the core 12. Around the core 13 there is a single-turn winding 19 carrying the motor current. In the main air gap 14 there is a movable permanent magnet 22 coupled to a control pedal for the motor. Initially the transductor is fully saturated by the control magnet, thus inhibiting pulses to the thyristor, until displacement of the magnet from the position between poles 15 reduces the saturation and increases the pulse repetition rate. The transductor also tends to be saturated by the winding 19, to prevent the supply of "on" pulses until the motor current decreases to a safe value. The winding 18 is connected across the base and emitter of a transistor and is energized by pulses from the shaping circuit, the arrangement being such that the transistor is cut-off to prevent the application of firing pulses to the thyristor when the impedance of the winding 18 is low due to saturation.

Abstract: 915,489. Control of D.C. motors; controllers. YALE & TOWNE MANUFACTURING CO. Jan. 18, 1961 [July 11, 1960], No. 2025/61. Class 38 (3). The speed and direction of an industrial truck having two reversible traction motors are controlled by handle 40 mounted for universal pivoting and actuating spring-biased rods 42 associated with controller-portions 36-39. Assuming that the handle is moved to actuate contacts 36-1, 37-1, these contacts first engage dead contacts 36-D, 37-D, to prepare the starting circuits of the motors in the forward direction. The contacts 36-1, 37-1 are now interconnected through lead 45, so that, if one of the live contacts 36-L, 37-L, is inadvertently engaged before the other, the motors are energized simultaneously. This prevents erratic movement of the truck. Other combinations of two controller-portions 36-39 may be actuated to effect simultaneous energization of the traction motors whereby the truck may be driven in the direction of its axis or may be pivoted due to rotating of the traction wheels in opposed directions. Each motor is associated with two reversing relays, and with two relays for regulating armature resistance, these relays being controlled from the contacts of sections 36-39.
